冻胀

The conclusion has guiding significance for mastering the characteristics of frost heaving and thawing-settlement in salty soil area of Qinghai-Tibet Railway.

所得结论对掌握青藏铁路盐渍土地区冻土工程冻胀、融沉特性有着指导意义。

According to the characteristics of the hydrologic geology and the climate in the western region of Liaoning province, after inspecting the phenomenon of Aeolian roadbed road frost damage in recent years and found the phenomenon of the road frost damage include frost heaving, thaw collapse, the mud pumping, cracking, etc.

根据辽西地区的水文地质气候特征，考察了近几年的辽西地区风积土路基道路的冻害现象，发现存在的道路冻害现象有：冻胀、融沉、翻浆冒泥、开裂等。

The frost heaving and thaw settlement processes have the critical effects on the civil engineering in the cold regions. In the global scale, these phenomena still lead to the primary disaster problems, in despite of some progresses on the study of freeze-thaw action.

尽管冻土冻融过程的研究已经取得一些进展，但迄今为止，随冻融过程而发生的冻胀和融沉问题仍然是引起寒区道路工程病害比较突出的问题。

The thermal regime of soils along the pipeline route will be severely disturbed due to the heat exchange between the oil flowing in the pipeline and the ambient soils. Therefore, the oil pipeline will suffer from the frost heaving and thaw settlement.

原油输运过程中由于管道与周围土体之间发生的热交换，使得原有土层中的热交换机制被打破，冻土区常温原油管道工程基础将面临融沉和冻胀灾害的双重挑战。

In the experiment, we mainly analysis the module, frost heaving, thaw settlement in freezes under the condition to the subgrade soil, the soakage change rule have carried on the actual, and have carried on fast and slow experiment contrast analysis in several primary factors that affected the roadbed to freeze the characteristic: The initial moisture content, the freeze speed, the load and so on.

试验中，重点对路基土在冰冻条件下，回弹模量、冻胀、融沉、吸水量的变化规律进行了实测分析，并对影响路基冰冻特性的几个主要因素：初始压实度、冻结速度、荷载等进行了快速、慢速试验的对比分析。

It's also a best place of the gradient transfer both for external and internal heave chemical industry.

这也是一个最好的梯度转移为外部和内部冻胀化工等行业。

It will become loose when this rock is disturbed. The test result shows that, by compaction, fine sands and mid-fine sands of the rock possess the characteristics of non-expansion, weak freezeexpansion, exceedingly light perviousness and high shearing strength.

通过试验证实：细沙、中细砂经压实后，均有较好的压实性，不产生膨胀，属弱冻胀，极微透水，低压缩性，较高的抗剪强度，这些特性指标均能满足工程要求。

The later were formed by regelation on the lee.

背冰面的不规则裂隙则是由于复冰过程引起冻胀造成的。

But, as you would be reminded if you had the temerity to suggest as much in the heaving bars around St Mary's Street, they could not do it.

但是，正如你将被提醒，如果你曾竟然建议多在酒吧冻胀圣玛丽的街道，他们仍然无法做到这一点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
