水平力必须彼此平衡。

The <em>horizontal</em> <em>force</em>s must be equal to each other.

充分保证了支座上座板与梁体、下座板与墩台之间在水平力为设计水平承载力三倍时无相对位移。

Between the top board of the support and girder, between the bottom board and frusta when the level power is three times of the design horizontal supporting capacity.

同时在该边中心桌上向外施加一个水平力。逐渐增加该力到规定值或者至少有一个桌脚离地为止。

While exert a level force on the centerdeskof the edge, increase gradually to a specified value or onelegnear to the floor at least.

研究成果可供在水平力作用下的桩基工程设计时参考。

These results can be provided as a reference for design of pile foundation under lateral load.

首先根据金川二矿水平矿层的开采特点和地质及力学背景，将其简化为两端受水平力作用的弹性地基梁。

At first, the HOL was simplified as a mechanical model of a beam on elastic foundation according to its geological condition and cutting characteristics.

这个水平力按所计算的楼层以上建筑物总荷载的规定百分率进行估算。此值约为该总荷载的百分之十几。

Lateral forces are estimated as stipulated percentages of the total load of the building above the given floor. These are of the order of 10 percent of that load.
