Analysis and Safety Assessment of Lining Thickness Defects in Highway Tunnels
Authors: Jiang Xinghong , Li Ke
Published: March 2020

Linings are the main structure of a tunnel to withstand pressure from surrounding rock and their thickness is representative of their load carrying capacity. Tunnel lining thickness defects will have a direct impact on the long-term stability of the tunnel project. Existing research on lining thickness defects focuses on analysis of crown thickness defects using failure load as criteria and is applicable to theoretical research with a lack of guiding significance to actual projects. Based on the test results of lining thickness defects in multiple tunnels of the Liangping-Zhongxian Expressway in Chongqing, this paper covers analyses of thickness defect location and extent and numerical analysis of the effects of different thickness defects on structural performance. The analysis results show: under the same surrounding rock conditions the probability of tunnel lining thickness defects occurring at the hance is similar to at the crown; the probability of thickness defects increases as surrounding rock conditions worsen; when thickness defects exceed 10%, the thickness defect percentage is inversely proportional to the safety factor. The research findings are of practical significance and can provide guidance to NDT, defect treatment and safety assessment.
Scale Model Study on Water Seepage from Cracked Lining Structure
Authors: Ding Hao , Jiang Xinghong , Li Ke
Published: March 2020

The calculation of water pressure behind a cracked lining structure requires determination of the crack width, amount of water seepage and the value of water pressure. Regarding the relationship among lining structure crack, water seepage and water pressure, self-made concrete splitting specimens and Chongqing University developed cavitation acoustic shock test system are used to study water seepage in the specimens. The test results show: water pressure and crack width are main factors influencing water seepage; at a given crack width, excessive water pressure imposes local load on the lining structure, aggravating its cracking; when the crack is excessively wide, water pressure changes slightly but flow rate increases considerably affecting traffic in the tunnel. Meanwhile, increased pressure from surrounding rock compresses the crack in the lining structure and reduces flow rate. The study results can provide reference to treatment of defects in tunnels at different depths in different areas.

Authors: Shengzhong Wu , Xinghong Jiang
Published: March 2020

As a core component of urban public transport, rail transit must meet very strict requirements for operational safety. Constructing houses over an operating subway tunnel will result in changes in structural load. Improper design and construction would have bad social implications from structure cracking to tunnel collapse. In the context of Cangbai Road Community Building Project in Chongqing, analyses are performed of the performance of existing Line 6 section tunnel and Yuzhong connecting tunnel under axial force and bending moment and deformations of surrounding ground and structure during the project construction to assess the safety implications of the building structure on the existing tunnel structure underneath. The results show: the rail tunnel experiences a maximum horizontal displacement of 0.93mm and vertical displacement of 3.87mm during construction of the community building; after the community building is completed, the verified sectional factor of safety is 2.9 and maximum crack width is 0.18 for Yuzhong connecting tunnel and the sectional factor of safety is 3.0 and maximum crack width 0.11 for the rail tunnel, meeting specified control requirements. Through strict construction control and intelligent monitoring measurement, main structure of the project has been completed without inducing any rail safety accident. The successful development of this project provides helpful experience to similar projects and more reference for multi-purpose development of urban land.

Authors: Chen Juntao , Hao Kun , Chen Jiabao , Ma Jianyun
Published: March 2020

Numerical simulations are carried out to study the seismic response of a subway station in rock and soil strata. In addition, during the numerical simulation, Drucker-Prager yield criterion and the constitutive model for concrete are introduced to be able to adequately describe the yield failure of surrounding rock and damage behavior of concrete. Based on the numerical results, the time histories of principal stresses, distribution of principal stresses at particular moments, the plastic deformation of surrounding ground and the damage of structure are fully studied. According to results and discussion, it can be concluded that the largest tensile stress generally occurs at corners including the spandrel, top of sidewall and the bottom of the sidewall. In addition, large shearing deformation is observed at the interface of rock and soil layer, due to the incongruous deformation. Structure damage is mainly observed at corner area in symmetrical distribution.

Authors: Yu Shun , Xiao Bo , Zheng Xixi
Published: March 2020

A building site consists of a garage and two super-high-rise towers. Two-way six-lane municipal double-arch tunnel and single-tunnel double-line long-span metro tunnel overlap above and below the building site. Finite element software is used to simulate the influence of surface construction on the two tunnels. The calculation results show that the construction above the tunnel has little influence on the structural deformation of the two tunnels, and the structural displacement of the metro tunnel meets the requirements of the safety control index of the rail transit structure; because the metro tunnel bears large rock, soil and building loads above, the structural design of the metro tunnel should be strengthened to meet the bearing capacity requirements.
