工程地质调查

By introducing damage tensor and net stress , this study has analyzed the mechanical properties of rock mass structural plane , hi this way , the rock mass question is macroscopically transformed into one of continuous medium mechanics , hi the light of the engineering reality in chengchao iron mine , the damage tensor of the area under research has been obtained on the basis of engineering geological survey
通过引入损伤张量和净应力来分析岩体结构面的力学特性，从宏观上将岩体纳入连续介质力学的范畴来处理。结合程潮铁矿实际，在工程地质调查的基础上，求得研究区域的损伤张量。
Based on the engineering geological survey of these two expressways the physical dynamics character indices and the standard bearing forces of each soil layers as well as the total settlement of the ground soil were determined and worked out . studies show that subgrade bearing forces of some sections from both expressways could not meet design requirement . the general settlement and difference settlement form greater hazards and need treatment
依据宣大、京秦线的工程地质勘查资料，确定各土层的物理力学性质指标、各土层的标准承载力，并计算地表土的总沉降量，表明这两个项目中均有个别段落的地基承载力不能满足设计要求，总体沉降利差异沉降危害较大，需要处理。
