【摘要】 通过对兰渝铁路沿线地质环境进行研究,总结分析复杂工程地质问题的特征,为类似工程的设计与施工提供指导。研究表明兰渝铁路经过区域地质构造、不良地质及特殊岩土极为发育,且处于高地震烈度及极高地应力区,地质环境极为特殊复杂。施工中所遇到的软岩大变形及流砂等属于特殊复杂地质环境引发的工程地质问题,需在科研的基础上进行特殊设计。更多还原

【Abstract】 Through research on geological environment along Lanzhou-Chongqing Railway,this paper summarizes and analyzes the characteristics of the complex engineering geological problems so as to provide guidance for the design and construction of similar projects.The research results show that the adverse geology and the weak rock and soil are developed considerably along Lanzhou-Chongqing Railway,where the seismic intensities are high and the crustal stresses are extremely large,so the geological condition is extremely complex.Furthermore,belonging to the engineering geological problems caused by peculiar and complex geological environment,the large soft rock deformations,drift sand and so on which were encountered in the process of construction,should be designed specially on the basis of scientific research.更多还原
