stress path of soil
解釋
土應力路徑-
The main problems widely seen in the previous studies are ( 1 ) inadequate modeling of initially anisotropically consolidated soil and ( 2 ) numerical vulnerability associated with the stress path in the vicinity of the failure line
以前模型普遍存在的問題有： （ 1 ）不能模擬初始偏壓固結的情況； （ 2 ）當應力路徑接近破壞線時數值穩定性差。 -
Four types of constitutive models are provided by the code : linear elastic model, duncan - chung model, nonlinear elastic model taking stress path into account and modified three - element model. contact element is used to simulate possible sliding between soil and structure. with this code, analysis is made concerning the pore pressure dissipation, lateral deformation of the support, ground settlement, bottom heave, and variation in earth pressure and support forces ; both effects of consolidation and coupled effects of consolidation and creep are considered ; furthermore, different combinations of cohesion, permeability and excavation width are elaborated
該程序採用了更合理的開挖荷載的計算方法，可以引入線彈性、鄧肯張非線彈性、考慮應力路徑的非線性彈性和修正三元件模型等四種本構模型，並在擋墻和土之間設置薄層接觸面單元以模擬土體和墻體在開挖過程中可能產生的滑移。 -
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
本文討論了隧道施工過程中，由於應力狀態的變化對土性的影響， ，隧道施工之所以造成地表沉降和地層損失，是因為隧道施工過程中以及隧道施工結束後土層的應力狀態已經不是原始應力狀態，因此在選用連續介質力學方法對隧道施工進行變形和穩定性分析時，必須採用實際應力路徑下強度參數。 -
The soil ' s stress path has important effects on the retaining wall ' s lateral deformation and the soil ' s deformation during the excavation of foundation pit. an experiment simulating the soil ' s stress path behind the wall has been carried out with the stress - controlled triaxial instrument. the principle stress ratio keeps constant during consolidation and the soil samples are permitted to drain during unloading process
利用應力式三軸儀對基坑開挖過程中圍護結構后側土體變形影響較大的因素：土體的應力路徑進行了試驗模擬，試驗是在等主應力比固結后側向卸荷而軸壓不變的排水情況下進行的。 -
In design of retaining structure, the reliability of the computing results relies mainly on the proper selection of shear strength parameters ( c and ). so it is exigent to devise a set of experiments according to the actual stress path of soil to determine its shear strength parameters
在基坑支護設計中，計算結果的可靠性在很大程度上取決于抗剪強度參數（粘聚力和內摩擦角）的正確確定，所以根據土體的實際受力過程做出合理的測定土抗剪強度參數的試驗設計已經成為十分迫切的任務。 -
