挡土墙

The sliding wedge, behind the retaining wall of not reaching the limit displacement, can be divided into numerous differential slices paralleling to the sliding plane. Then, with the force analysis of these differential slices and the relationship mentioned above, equations can be set up and the inclination of the sliding plane is also derived. Thereby, the calculation formula of the nonlimit active earth pressure is obtained.

对于未达到极限位移的挡土墙，结合已取得的位移与摩擦角之间的关系，采用与滑裂面相平行的微条对墙后滑动楔体进行划分，对微条进行受力分析，建立平衡方程，推导了滑裂面的倾角，从而得到非极限主动土压力计算公式。

Well-suited for applications such as reinforced slopes, basal reinforcement, temporary walls for staged construction and surcharging, and for modular block faced walls, extensible reinforcements are used primarily in commercial and residential applications where the possible elongation of the reinforcement and resulting lateral deformation can be tolerated.

Based on Mononobe-Okabe＇s postulation and the reasonable consideration for the restricted pore water, a first-order differential equation of the dynamic active earth pressure on rigid retaining walls with submerged backfills in the traaslational movement mode under earthquake loads is set up by using the method of level-layer analysis.

基于Mononobe-Okabe假定，在合理考虑土体孔隙中受限水含量的基础上，利用水平层分析法推导了填土中有地下水时刚性挡土墙平移模式下的动主动土压力强度的一阶微分方程，并求得非线性分布解：探讨了地下水位、受限水含量、填土的内摩擦角、墙背的摩擦角和地震系数等参数对土压力强度分布、合力作用点高度以及倾覆力矩的影响。

Because the major load bearing on retaining wall is soil pressure, the Coulombs theory of soil pressure, which is often used in engineering, is adopted to calculate the magnitude and the action point of soil pressure.

由于挡土墙所承受的主要荷载是土压力，因此采用工程中普遍使用的库仑土压力理论来计算土压力的大小和作用点。

Considering the progressive rupture mechanisms in backfill of different movement modes, the modified Coulombs solutions of active earth pressure were used to calculate the lateral earth pressures, the total lateral forces and their applied points. Comparisons of the calculated results with observations from model tests show that the prdposed methods can provide good predictions of earth pressures for different wall movement modes.

同时，根据不同位移模式下墙后填土渐进破坏的特点，对库仑土压力计算方法进行不同的修正，并引入摩擦角与位移之间的关系，得到不同墙体位移模式下任意位移时挡土墙上水平土压力强度大小、分布，水平土压力合力大小及合力作用点。

And that the model type ranges from gravity to transitional and to plane retaining wall when the diameter of cylinder increases.

筒内填料抗倾模式由重力式逐渐向过渡式、平面挡土墙式变化。

Because of the concern remained about the credibility of embankment and retaining wall built along the housing development, the foundation was laid on natural ground beneath the lower tier which was more reliable as the supporting stratum.

由于对周边开发建筑的堤防和挡土墙信誉度的关注，后建筑的地基就建在了天然地面上，作为支撑层更加可靠。

2 In such circumstances the Contractor shall be required to use steel trench sheeting or steel sheet piling or some other retaining wall system adequately supported by timber struts, wailings, etc.
