路基

Some of these were dug into the ground, while others were deployed behind walls or creek embankments.

一些被埋在土里，其余的被放置在后墙或河流路基上。

So it's very necessary to increase the height of the embankments about 45-80cm, with an average about 60cm.

因此，有必要适当地提高路基高度，提高45～80cm，平均60cm左右。

CLASSIFICATION OF MATERIALS FOR USE IN THE CONSTRUCTION OF EMBANKMENTS AND CAPPING LAYERS OF ROAD INFRASTRUCTURES.

土方工程。道路基础的路基结构和岩层中用材料的等级

But this time,"ground-based midcourse missile interception".it is the GMDtest !Not a THAAD.

但是这次测试的是路基中段导弹拦截，这是陆地中程导弹防御系统测试，不是高空防御测试。

Because most motorcyclists drive well to the left.

因为大多数骑车者靠着路基走

This paper states main roadbed fault in Heilongjiang province——frost heave, freezing and expanding, and raises its prevention measure.

本文记述了我省公路路基的主要病害—翻浆和冻胀阐述了其产生的原因及设计、施工中的预防措施，并对提高公路使用年限很有帮助。

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。

The principle of railroad trackbed inspection with GPR mounted on track vehicle is introduced. In line with requirements of exploring depth, accuracy and speed in the process of field survey, the layout of GPR survey line is put forward, the center frequency of antenna, the maximum time window, the temporal sampling interval and the space between traces are calculated according to the theoretical formulas.

介绍了使用路检车装载探地雷达对铁路路基检测的原理，结合野外探测过程中对测量深度、精度和行车速度的要求，给出了GPR现场工作测线布置的原则，理论上给出天线中心频率、时窗、采样率、测量点距的计算公式。

The engineers and technicians determine reasonable design parameter, choose wellbehaved construction equipment, draw up operable construction procedure and a set integrated quality system by test in the process of making use of grouting penetration method treating foundation dent.

在采用压力注浆法治理公路路基塌陷时，需要通过注浆试验确定合理的设计参数、选择性能良好的施工设备、制定切实可行的施工工艺以及一套完整的质量保证体系。

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％。
