in-situ stress
reservoir stress
Examples
- Distribution laws of stratum stress with working face excavation in subway tunnels
城市地铁隧道工作面开挖的地层应力分布规律 - Centrifuge model test technique preferably solves two problems : one is the gravity loss of the model soil , the other is the coupling problem between the seepage field of the ground water and the stress field of the stratum , which is a guidance for other deformation controls under the similar condition
离心模型试验技术较好的解决了在地下工程研究中模型土体的自重损失和地层位移分析中地下水渗流场和地层应力场相互耦合作用问题，对于在相似条件下富水地层隧道开挖施工如何控制地表沉降变形的研究方面具有指导意义。 - The thesis introduces the biot ' s three - dimension consolidation theory based on absolute linear - elastic theory ; the thesis designs the pit dewatering scheme of hand - dug piles support of shenyang subway ' s shenyang station construction ; the thesis uses finite element program to simulate the influence on around environments caused by pit dewatering , and finds the change laws of earth mass inner stress and the effect parameters on the surface deformation on the basis of reasonable hypothesis and the analysis of ground water exploitation progress . combined with stochastic medium theory , the thesis introduces dewatering subsidence coefficient , sets up the predicting model of the surface deformation caused by dewatering , and develops the computing program ; by application of program on a single well of underwater exploitation , it is proved that the program is feasible , so the prediction of the surface deformation caused by underwater exploitation is realized
