Before 1920 attention was focused largely on the pavement or other wearing course , and little notice was given to the materials that made up the subgrade or to the manner in which they were placed or compacted .soon after that date increased vehicle speeds brought demands for higher standards of alignment and grade ,which in turn meant deeper cuts and higher fill .

1920年前关注主要集中在人行道上或其他穿着当然，小通知书交给了材料，取得了路基或以何种方式被放置或压缩。尽快在该日期之后增加了车辆的速度要求更高标准的一致性和等级，这反过来又意味着进一步削减和更高的填补。

The results show that the depth of the traffic loads affected is about 2 meters in both subgrade and retaining wall. Under normal circumstances (fully loaded heavy vehicles, driving on a carriageway), the dynamic earth pressure of prestressed anchor sheet-pile wall is approximately 10% of earth pressure at rest.

结果表明：交通荷载在路基与挡墙中所反映的影响深度大致都为2m左右，正常情况下（重型汽车满载、行驶在行车道上）作用在预应力锚索桩板墙上的动土压力大约为该处挡墙静止土压力的10%。

Comparative analysis the reinforcement result of the instantaneous and step by step preloading and the state of setting up the plastics drain board (different spacing or different length). It has offered the objective basis for the research and analysis of the subgrade settlement and the consolidation steadily further.

比较分析瞬时加荷与逐级加荷以及塑料排水板不同设置状态（不同间距时，不同长度时）的加固效果，为进一步研究分析地基压缩沉降和固结稳定以及塑料排水板布置方式的优化设计提供了客观依据。

And prevent subgrade form frost heave and frost boiling.

并起到预防道路冻胀和翻浆的作用。

According to several diseases caused by seasonally frozen soil subgrade,this paper discussed the seasonal permafrost roadbed on the causes,and introduced several methods to resolve the frost heave disease briefly.

根据季节性冻土地段路基出现的几种病害，论述了季节性冻土路基产生的原因，简要地介绍了几种解决冻胀病害的方法。

This paper studied an electronic-hydraulic servo force loading system, which is applied on frozen soil frost heave experiment. This system simulates the pressure acted on the subgrade by train in low temperature situation.

本文以应用于冻土冻胀试验的电液伺服力加载系统为研究对象，该系统在一定低温条件下，模拟火车运行时给路基带来的压力。

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）。
