摘要
根据内蒙古神华新街台格庙煤矿区TBM斜井施工过程中面临的高水压、大埋深、地质条件复杂等现状,采用非线性梁弹簧模型,探讨了埋深、水深、管片厚度、接头抗弯刚度及二衬厚度等因素对斜井管片结构受力特性、安全系数的影响,并提出了有关施工技术措施。
The status of high pressure, large buried depth, and complex geological conditions exist in the construction process of TBM inclined shaft in Shenhua Xinjie Taigemiao coal field in Inner Mongolia. Nonlinear beam-spring model is used to investigate the effects of buried depth, water head height, segment thickness, joint bending stiffness and secondary lining thickness on structure load characteristics and safety coefficient of shaft segments and related construction technical measures are put forward.
