This paper discussed about the changes of stress state on effect of soil properties . the reason of surface settlement and layer losses is that the stress state is not primeval one in and after tunneling construction . therefore it is necessary to select strength data in actual stress path in making tunnel deformation and stability analysis with continuous media mechanics 本文讨论了隧道施工过程中,由于应力状态的变化对土性的影响, ,隧道施工之所以造成地表沉降和地层损失,是因为隧道施工过程中以及隧道施工结束后土层的应力状态已经不是原始应力状态,因此在选用连续介质力学方法对隧道施工进行变形和稳定性分析时,必须采用实际应力路径下强度参数。
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。
