Abstract: The present invention provides a tunnel forming construction method using a large core fracture-type unit structure which bores only an edge portion in comparison to a TBM boring method requiring a long period of time by boring an entire front area in a small gravel size to form a core in a form of a cantilever structure to quickly remove front rock by large-size fracturing using tensile force to greatly increase an advancing speed. The tunnel forming construction method comprises: a step (A) in which multiple ′leading boring unit structures′ independently move on a ′leading boring part′ and make an entry space of a ′casing structure′; a step (B) of injecting grout into a ′partitioned grout space′ on the rear surface of the ′leading boring unit structures′ to block the transfer of frictional force to ′surrounding ground when the casing structure moves forward′; a step (C) of moving the ′casing structure′ into an entry space of the ′casing structure′ created by the ′leading boring part′ by hydraulic force and moving the remaining core into the structure; a step (D) of maintaining a repose angle and using tensile force to remove the core moved into the ′casing structure′ in a large size and transport the core backwards; a step (E) of additionally cutting the core transported backwards in a transportable size in an assembled tunnel; and a step (F) of assembling new segments in an assembly space whose outside is protected by ′partition grout′. The steps A to F of all processes are coupled to create a single organic movement, and the processes independently and simultaneously operate to increase work efficiency by continuous work in which limitations for each process step do not exist.

IPC: H03M13/37
Filed: 2018-11-09
Abstract: The present invention relates to a multiple-vote symbol-flipping (MVSF) decoding method for nonbinary LDPC codes. According to the present invention, the MVSF decoding method suggests a criterion for determining the number of variable nodes sending two candidate symbols to each inspection node on every repetitive decoding process. According to the present invention, the MVSF decoding method finds a symbol having the largest message to all the variable nodes and a symbol having the second largest message and calculates a message difference between the symbols, and then, transmits the symbols to a connected inspection node only when the message difference is smaller than a specific threshold value. According to the present invention, the MVSF decoding method suggests a method of adaptively selecting a threshold value about a message difference depending on the number of repetitive decoding times. Consequently, the threshold value is determined with a function of the number of repetitive decoding times. According to a computer experiment result, a nonbinary LDPC code decoded through the suggested method has better error-rate performance than an existing decoding method.
