地基

Cushion is a key technique of composite foundation, which is designed by experience now.

这种局面如不有所改观，必然阻碍复合地基技术的发展。

Therefore, abutment stability analyses and foundation treatment are the key to success in constructing arch dam or not.

因此坝肩稳定分析和坝肩地基处理是修建拱坝能否成功的关键。

The idea of building a castle in the air－with no foundation at all－is, of course, ridiculous.

因此，在空中建造没有地基的城堡的想法是非常荒唐的。

To correct direction, first only the air hammer among located in the position corresponding to the correcting direction is actuated and only the ground in the correcting direction is drilled by a predetermined amount.

在方向修正时先仅使其位置与修正方向相对应的气锤工作，仅对该修正方向的地基按规定量进行挖掘。

The system is reportedly 100 percent silent and extremely difficult to track by air on ground-based radar systems.

这种系统据称还是完全静音的，地基或空基雷达很难探测到。

The ground measurements of albedo at Grz are used to validate the satellite data.

首先 ，利用改则自动气象站的地基观测对MODIS地表反照率进行了对比验证。

ABSTRACT Soil-structure dynamic interaction is the dynamic responding of soils, foundation and superstructures excited by wave propagation ...

土—结构动力相互作用的本质就是波动在结构-地基系统内传播时引起的结构和地基的动力反应问题。

However, a vast amount of research demonstrates that dynamic interaction has a great influence on the dynamic characteristics of superstructures, and interaction system seismic response may greatly change.

然而，大量的理论分析和研究表明，在地基土质较差的情况下，地基-基础-上部结构动力相互作用对结构物的动力特性具有十分重要的影响，其地震响应将发生显著的变化。

Groundwork theodolites are widely adopted in home, theodolite is built in immovable groundwok seat, which is specially designed according to definite azimuth geography coordinate based on the need of shooting range stand.

国内靶场装备的经纬仪大都采用固定地基式，把经纬仪安装到固定的地基座上，地基是根据靶场布站的要求，按照一定的地理坐标而专门设置的。

In order to help for evaluating properties of soil in interaction more precisely, the paper applies elastic theory solution on different modulus in tension and compression for vertical load into semi-infinite elastic body. Through quoting Heaviside function, the solution of elasticity theory with different modulus in tension and compression is established founded on the solution of elasticity theory for the material incapable in tension and Mindlinsolution for equal modulus.

为使地基土在共同作用中的行为特征评价更为合理，本文应用了半空间问题竖向荷载下地基土的拉压模量不同弹性理论解，该理论解是通过引入Heaviside函数，利用不能承受拉应力材料的弹性理论解并结合拉压模量相等的经典Mindlin解而获得。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
