冻胀

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。

In chilly area, many civil engineering projects have to face the problem of ground frost heave, which can cause unevenness of highway, railway, airport runway and etc. as well as displacement of underground piping, even damage of building foundation construction.

在严寒地区，多种土木工程的应用都需要面对地面冻胀这一难题，此问题的发生会导致公路、铁路、机场跑道等高低不平，底下管道移位，甚至会令房屋的基础结构受损。

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。

Strength of the water-rich rocks increases with the decrease of temperature which is mainly due to the peak intensity of rocks greatly improved by mineral contraction and ice strength and frost heave force with temperature decreasing.

强度随温度降低而增大的主要原因是温度降低时，岩石冻结时的矿物收缩和冰本身的强度及冻胀力使得富水冻结岩石的峰值强度得到提高。

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。

In order to prevent frost heave of hydraulic structures, the measures such as drainage, protecting and cutting-off migration of capillary water should be also comprehensively paied attention to.

由此阐明了工程界直接利用一定的约束压力即可有效地消减冻胀的理论依据。并指出水工建筑物的冻害防治还应采取排水、隔断毛细水、保护等综合性措施。

Based on analysing the differences between artificially frozen soils and naturally frozen soils and comparing the present testing devices for the study of frost heave and thawing settlement at home and abroad, a new device for studying the frost heave and thawing settlement of artificially frozen soil was developed.

并利用该试验装置对徐州地区常见的粘土进行了冻结试验，检验了该试验装置的可靠性和实用性；得出了人工冻结土体在冻融过程中土体在垂直方向上的冻胀远小于它在该方向上的融沉等几点结

"Frost resistance design code for hydraulic structure"and" frost heave resistance design code for canal system engineering"are compared and analysed.

对《水工建筑物抗冰冻设计规范》和《渠系工程抗冻胀设计规范》不同特点做了对比分析，指出按各自的标准进行计算会给工程设计带来不同安全度，建议宜协调一致，以利工程设计遵循。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
