对“复合结构刀的位移本文根据力作用的独立性原理,分别按三种情况进行计算,然后叠加。第一种情况,界面上的竖向荷载以及体积力的作用、按平行墙理论计算;第二种情况是复合结构受侧压力作用,按弹性理论检算应力状态,而位移用材料力学给出的解已足够精确;第三种情况是墙被视为刚性体,在侧压力作用下产生的位移。竖向地基系数采用 m_0y。对锚定板桥台的位移,本文引用地基侧向抗力系数计算锚定板前侧的土抗力。并假定墙背土压力与位移呈直线比例。由此导出平衡条件并求解位移。
According to the principle of independence of force, this paper calculates and then adds them according to three kinds of situations respectively: In the first case, the vertical load and the effect of body force on the interface are calculated according to the theory of parallel walls; In the second case, the composite structure is affected by the lateral pressure and the stress state is calculated according to the elastic theory. The solution given by the mechanics of the displacement material is sufficiently accurate. The third case is that the wall is regarded as a rigid body. Under lateral pressure, The displacement of the anchor foundation is m0y.For the displacement of the anchorage plate abutment, this paper uses the foundation lateral resistance coefficient to calculate the soil resistance on the front side of the anchor plate, and supposes that the pressure of the soil on the back wall is linearly proportional to the displacement. Derive the equilibrium conditions and solve the displacement.
