Authors: Li Chao , Ren Guo Chun , Wang Cheng Gui , Wang Yu Bo
Published: October 2013

In this paper, we propose to apply a centre scheduling algorithm in the CRAHNs with a cluster. In this network, the cluster head assigns time slots to each node so that every node can be fair to transfer data. The scheme schedules the links to the same destination node first, which has the largest topology structure, then another destination node whose topology structure is larger than the rest. The algorithm presented in this paper considers both the fairness and the spatial reuse, and the simulation results show that this algorithm still has a good performance when the topology is so large.

Published: October 2013

The later-period structure of Fuyang oil layer is complex and its reservoir is mostly composed by the sand bodies of riverways. The oil and gas reservoir features obvious concealment, and also is difficult to identify. To accurately describe the reservoir, a post-stack spectrum imaging was made for the identification of the riverway sand bodies in Fuyang oil layer using EPSTM image in the study area. The statistical error of the riverway sand body identification result using post-stack spectrum imaging was small if the sandstone thickness was greater than 3m. Seen from logging wells geological verification, the riverway identification fit rate was 81.6% on average, the microfacies type identification fit rate was 75%, and the microfacies types identification fit rate of the sandstone thicker than 3m was 80%. Using the nonlinear algorithm of the MDI software, the lithologic prediction was implemented based on the sand group as the unit, and the average prediction fit rate of the sandstone thicker than 3m reached 90% according to the standard relative error less than 20%. Therefore, the post-stack spectrum imaging can exert a significant effect for the anisotropic reservoirs of complex later-period structure, thin sand body, and complex changes, and can meet the needs of the oil field exploration and development to some extent.

Published: October 2013

This study is concerning the influences of nitrogen content and aging precipitates on pitting corrosion resistance properties of high nitrogen austenitic stainless steel (HNS) through potentiodynamic polarization method. The microstructure of aged HNS is analized by scanning electron microscopy (SEM). The main results obtained are as follow: the formation of intergranular, cellular Cr2N and intermetallic χ precipitates makes the depletion of Cr and Mo in the matrix and deteriorates the resistance to pitting corrosion in aged specimens. Cr2N starts to precipitate in the form of lamellar structure to cellular precipitates, the pitting corrosion drops to about 0 VSCE. HNSs perform the same tendency that the pitting corrosion potential firstly decreases then increases and reduce to the minimum value at nose temperature. All the pitting corrosion potential of HNS-B aged for 2h at different temperature presents more than that of HNS-A. The pitting corrosion resistance is mainly controlled by nitrogen content before great precipitates of cellular Cr2N and intermetallic χ phase rich in Cr and Mo. It is also mainly controlled by the content and the type of precipitates after great precipitates of cellular Cr2N.

Published: October 2013

In engineering quality inspection and acceptance and evaluation of structural properties, the quality of structure real object is paid more and more attention to by all parties involved in construction. But the structural detection technology and corresponding rules are lagging. Through the use of the same batch of concrete structure and frost resistance of concrete test block test, the results show that for the same concrete mix, the frost resistance of standard preserved test block is better than that of the core samples drilled from concrete; as for the mixture ratio, the forming and curing conditions are exactly same as the concrete, and the preserved test block frost-resistance performance is also superior to that of concrete core-sample.
Finite Element Analysis for Subgrade Consolidation Settlement in Soft Soil
Authors: Tan Feng , Zhou Tai Quan
Published: October 2013

The two-dimensional finite element model for subgrade consolidation settlement analysis within soft soil pile is developed using ABAQUS. The numerical simulation on a highway subgrade deformation is performed to study the variation of consolidation settlement and the excess pore water pressure distribution in the central location and the part under centerline of the embankment. The results show that settlement develops gradually with the increasing period of soil consolidation. The excess pore water pressure of deep subgrade soils under embankment centerline rise due to the increased load. After each soil layer was filled, the excess pore water pressure increased in the first and was stable later along with the increase of soil depth. After the embankment soil was filled completely, excess pore pressure dissipated with time developing until the completion of consolidation.

Published: October 2013

The corrosion behavior and fracture mechanisms of rock wool have been studied. After different corrosion test, morphologies of rock wool fibers were obtained using SEM. The leaching rate of non-siliceous cations was measured using ICP-MS. Elemental analysis and the structure of the fiber surfaces were investigated by SEM-EDS and XRD. The results revealed that the corrosion of rock wool fibers in sulfuric acid solution was primarily attributed to calcium, magnesium and aluminum ion depletion. Rock wool fiber dissolution begins by the exchange of network modifier ions via metal-proton exchange reactions, then a partial removal of network intermediate ions by Al,Fe-proton exchange reactions followed by the liberation of partially detached Si tetrahedrals.

Under the effect of geologic hazard, soil horizon under gas pipeline tends to subside or runoff, which may result in pipeline hanging in the air with uneven distribution of stress and consequently lead to pipe failure. In view of pipeline suspension resulted from geologic hazard and taking pipeline XX as example, software CAESAR II is used to analyze the stress of suspended pipelines with different length combined with practical and existing analysis calculation model. The critical length of suspended pipeline is obtained on the basis of the software analysis. The results with certain engineering value can provide reliable theoretical basis for practical engineering.
