On the safe side, we should use active soil pressure and passive soil pressure to calculate the support strength before T increased. That is RA=EA-EP Among them: RA ………… holding strength EA ………… composite force of active soil pressure EP ………… composite force of passive soil pressure Immediately, flexural torque distribution of enclosure wall can be counted. Mmax is the location of shear force zero. Equivalence beam method abridges. No matter which kind of supporting structure form, the key problem lies in the establishment depth of catch point, severity of support and enclosure wall, penetration depth and pit bottom quality of soil property.

单道锚杆支护结构计算分别采用静力平衡法及等值梁法，根据试算法插入深度t值需先进行假定墙的插入深度确定后来计算支撑力，为了安全起见，可按插入深度增大前的主动与被动土压力合力计算支撑力即 RA=EA-EP 式中：RA …………支撑力 EA …………主动土压力合力 EP …………被动土压力合力随之可求围护墙的弯矩分布，Mmax为剪力为零点的位置，等值梁法的计算略述。

主要针对312国道镇江段香草河大桥和汤龙公路大桥采用先简支后结构连续部分预应力砼组合箱梁的施工中，在底板制作、钢筋绑扎、混凝土浇筑、预应力张拉、箱梁安装、组合体系转换等方面所采取的质量控制措施，本文分析对比了两座桥施工中好的做法及出现的质量缺陷，提出一些防治、处理措施及建议。

Nowadays, this structure is widely used although its design theory can not keep up with its engineering application. With the development of the west regions,with the construction of more infrastructures e.g. railways、highways and water conservancies, this kind of retaining wall will be more popular. So this paper does a research on this retaining wall based at a practical site.

目前这种结构应用较为广泛，但是其设计理论相对滞后于工程应用，随着国家西部大开发战略的实施，更多的铁路、公路和水电等基础设施项目陆续投入建设，桩基托梁挡土墙支挡结构也将大量应用，所以本文结合实际工点对桩基托梁挡土墙结构进行了研究。

This paper is concerned with the vibration responses of an infinite, fluid-loaded, elastic foundation of Bernoulli-Euler beam under the convected forces.

本文即是探讨柏努力－欧拉梁受这移动外力作用下的振动分析；并考虑梁的流体承载与弹性基础的反弹力效应。

After being prefabricated, they will be carried to the point, and installed on the bridge. Seated very close to each bridge, prefabrication sheds are responsible for prefabricating girder boards and culvert cover boards. Dadoes are set up according to the number of girder boards. Two joist barrows and one 315KVA power transformer are fixed in prefabrication shed .

The results show that the key rock-beam situated at the outside of the structure acts as a framework, shielding and interdicting the transference of stress. This is true not only in the vertical but also to a great extent in the horizontal direction as well.

结果表明：外层关键岩梁结构在巷道变形过程中起到骨架作用，屏蔽和阻断应力的传递，不但使得巷道跨度范围内垂向应力的传递发生阻断，上部岩层载荷不能向关键岩梁下位岩层传递，而且承担了开挖引起的应力重分布的大部分水平应力。
