Analysis and countermeasures disease in cement concrete bridge surface layout;2. Because of the substandard control of height in bridge pile base construction,it leads to the unfitness in bridge surface slope and design.

在进行桥梁桩基施工时由于标高控制不准，导致桥面横坡与设计不符，为保证桥面的横坡与前后路基的一致性，确保行车的舒适安全，对桥梁桥面横坡的处理方案进行了分析探讨，并提出了切实可行的处理方案，可给今后类似桥梁问题的处理提供参考。

In this article, introducing subgrade max dry density and optimum water content, it introduces site density experiment methods（including cutting ring method, sand replacement method, applicable condition）instrumentand procedures.

本文在介绍路基土、路面基层最大干密度及最佳含水量方法的同时，还对目前现场密度试验普遍采用的方法：环刀法、灌砂法、核子湿度密度仪法适用条件、仪器、方法步骤等做了详细介绍。

As a result of this, according to the paper, the frozen layers have spread upward in some places, freezing the dirt infill of the rail bed itself.

因此，冻土层在某些地方向上扩展，冷冻了路基下的泥浆。

The thesis right aims to the middle frozen climate and geology condition and study general theory of subgrade drainage and specialties for the kind of area.

介于我国目前公路建设任务的重心已转向地域广阔的西北中冻地区及沙漠地带，本研究成果对该地区新建公路设置完善路基排水、提高公路使用寿命具有参考价值。

Because the roadbed is in the condition of stable seepage in the normal highway construction and service, the formula of level and discharge of cut, tunnel and drainage structure in condition of confined water and dive are deduced on the saturated seepage theory.

4由于在公路建设和运行中，绝大多数时间路基是处于稳定渗流的情况，根据饱和渗流理论，推导建立了在潜水和承压水条件下路堑结构、隧道结构和排水设施在稳定渗流情况下的水位和流量计算理论公式；按地下水类型、公路结构型式、排水设施型式、是否进行衬砌或支护、组合方式和布置方案构建了公路工程地下水稳定渗流模型。

Because the roadbed is in the condition of stable seepage in the normal highway construction and service, the formula of level and discharge of cut, tunnel and drainage structure in condition of confined water and dive are deduced on the saturated seepage theory. The stability groundwater seepage model of highway engineering is established according to groundwater type, highway structure pattern, drain facilities pattern, whether carried on lining or timbering, combined pattern and layout.

The calculation results show that the effect of tide and back berms on the consolidation process is obvious.

计算结果表明潮汐、反压护道等对淤泥路基排水固结过程有显著影响。

The calculation result showed that the effect of tide and back berms on the consolidation process is obvious.

计算结果表明，潮汐、反压护道在淤泥路基排水过程中均有显著作用。

In this paper,a detailed analysis of the causes of the breakages is carried out. The discussion is mainly focused on the stability and strength of subgrade, the selection and construction of base course materials, the quality control of pavement concrete,the control of the mixture ratio of the concrete materials and the technological control in the process of construction.

文章着重从路基的稳定和强度、基层结构材料的选择和施工控制、路面混凝土的材料质量控制、施工中的混凝土配合比控制和施工工艺控制等角度对路面破损产生的原因加以分析。

Engineering geological conditions are quite good, supporting the roadbed, bridges and culverts and other artificial structures.

工程地质条件较好，对路基、桥涵及其它人工构造物较为有利。

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％。
