2 .深入分析了土體的彈性模量，水泥攪拌樁的彈性模量，水泥攪拌樁擋墻的寬度，土釘長度的變化以及土釘傾角的變化對復合型土釘墻變形性狀和土釘軸力的影響，以及水泥攪拌樁擋墻的寬度在淤泥土層以及砂土土層中對復合型土釘墻支護變形性狀的影響。This paper puts forward a method of fast, handy, no - destructive and effective testing which can be used to test the strength and geometrical dimension of subgrade abamurus using the method of earthquake wave velocity and gpr ( ground penetrating radar ). this method can be used to definite the dimension and strength of abamurus by determining some physical parameters ( such as elastic wave velocity and electromagnetic wave velocity etc, ) and by the correlation of these physical parameters with mortar flag stones
本論文提出使用地震波速法和地質雷達法檢測路基擋墻的強度和幾何尺寸，是一種快速、簡便、無損、有效的檢測方法。此方法通過測定某些適當的物理量（如：彈性波速度、電磁波速度等） ，並通過這些物理量與漿砌片石的相關性，確定墻體的尺寸、強度等性能。The main contents of testing the strength of subgrade abamurus using earthquake wave velocity are as follows : the influence of the lithology and strength of flag stones and the shape of block upon wave velocity, the influence of the strength of cement mortar upon earthquake wave velocity, the estimation standards of the strength and completion of abamurus. this paper puts forward an accurate no - destructive testing using the different reflect of elastic wave velocity for abamurus stones, the strength of mortar, the plumpness of mortar and the type of abamurus, on the basis of laboratory tests and field tests. it can be used to accurately distinguish the completion of abamurus
地震波速法檢測路基擋墻強度，研究的主要內容有：片石巖性和強度及塊體形體對波速的影響；水泥砂漿強度對墻體波速的影響；擋墻整體強度和完整性的評估標準。應用彈性波速度對擋土墻石材、砂漿強度、砂漿飽滿度及擋墻類型的不同反映，在室內外模型試驗和現場生產試驗的基礎上，提出了一種正確的無損檢測法，可以正確判別漿砂片石擋墻墻身的完整性。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。分享友人
