灾害

The research on cataclysmic law of underground engineering excavating disasters is the basis of research on prewarning system of underground engineering excavating disasters.

地下工程开挖灾害灾变规律的研究是其预警系统研究的基础。

This thesis study geological disaster of Heyang in the point of system.

本文以系统的观点，开展了合阳县地质灾害的研究。

They become the portents of social disaster and cultural loss.

他们成为portents社会灾害和文化的损失。

For most of China's long history, earthquakes and other calamities have been viewed as both portents of change and a test of the ruling government's "mandate of heaven."

在中国的漫长历史中，地震和其他大灾害被认为是改变的预兆，也是测试执政政府的&天命&。

Therefore, some land use policies,such as compiling land use planning in areas fragile to flood disaster, carrying out the policy of "conversing agricultural polders to lake, emigrants for town construction", developing "antiflood agriculture", constructing flooddiversion and floodstorage areas, and improving land use efficiency, etc, are proposed for mitigating flood disasters.

据此提出了中游地区减轻洪涝灾害的土地利用对策，如编制易灾区土地利用总体规划、实施&退田还湖、移民建镇&战略、发展&避洪农业&、建设分蓄洪区、提高土地利用率等。

Hazards of Budongquan migrating pingos can be decreased or protected by taking engineering measures as building underground water conduits or draining off the upward rushing spring water near ground surface.

采用适当的工程措施，通过地下疏导或地表排放沿断裂破碎带上涌的地下泉水，能够有效减轻或防治不冻泉移动冰丘的灾害效应。

There are six typical migrating pingo s along the Qinghai-Tibet Railway and freezing and swelling of some of these pingos caused fracturing of bridge piers and culverts and bending of oil pipelines along the railway and highway.

青藏铁路沿线发育6个典型移动冰丘，冰丘冻胀对线路工程具有严重破坏作用，导致桥墩扭裂、涵洞破裂与输油管道弯曲变形，产生显著的灾害效应。

And scale, height and covering area of Budongquan migrating pingos further increased in 2006. Budongquan migrating pingos not only piered and etched the highway, but also destructed the culvert, depressed ground surface, bended oil-pipeline and formed ground fracture zones.

不冻泉移动冰丘不仅穿刺青藏公路路基，破坏青藏公路桥涵结构，蚕食青藏公路路堤，影响青藏公路的交通安全；而且导致输油管道拱曲变形，诱发地面塌陷和地裂缝，产生显著的灾害效应。

Three dimensional numerical modeling on migrating pingo destructing bridge pier can provide important factors for designing bridge and protecting geological hazard in permafrost.

移动冰丘导致桥墩变形破坏的三维有限元数值模拟能够为常年冻土区桥梁工程设计和地质灾害防治提供力学参数和科学依据。

It is considered that the gas pre-extraction measure in coal bed is one of the most effective methods to prevent the gas disaster.

目前，本煤层瓦斯预抽放措施仍然被认为是预防瓦斯灾害最有效的方法之一。

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。
