Increasing the arch thrust augments the shear stress on the surface of the shearing resistance part, which counteracts the influence of the crushed rock.
同时由于拱向应力的增大，即增大了抗剪面剪应力，抵消了坝体下游破碎岩石的影响。
The non-abutment slant-legged rigid frame bridge is similar to mansard arch bridge, the soil pressure of the diagonal rod at both ends of bridge forms a couple of arch thrust.
无桥台斜腿刚架桥是一种新的桥型，因其适用、经济、美观等方面的独特优势，近几年在工程领域中已有较为广泛的应用，但理论研究相对滞后。
For high in situ stress occurred in Ertan dam area, combined action of initial in situ stress field, time and space effect during excavation and external loads arch thrust etc.
笔者针对二滩电站坝区存在的高地应力现象，从初始地应力场的建立、施工开挖的时空效应，直到与拱推力等外荷载共同作用下对坝基岩体稳定的影响全过程进行了分析和计算。
Because of asymmetry of side arch, the support for casting will bear tremendous horizontal thrust when placing side arch concrete.
由于边拱具有不对称性，因此浇注边拱混凝土时现浇支架将承受巨大的水平推力。
This paper also analyses the bending stiffness of arch, points out that the thrust of the neglect of axial compression deformation, can lead to thrust calculation error 30%.
本文还分析了压弯刚度对拱推力的影响，指出忽略拱的轴向压缩变形的影响，可导致推力的计算误差达到30%。
