哈尔滨地区地壳稳定性研究
|
摘要
客观评价城市区域地壳稳定性,对于城市安全与可持续发展有着极其重要的意义。哈尔滨城市地质调查系统地研究了哈尔滨地区的莫霍面深度、地球物理场、火成岩特征及历史地震记录,并开展大地电磁测深、钻探及汞气测量研究,认为哈尔滨地区地壳结构连续、完整、稳定,不会发生中等强度及以上地震活动。
Objective evaluation of regional crustal stability in a city is of vital significance to safety and sustainable development of the sity.Geological survey in Harbin was conducted to examine the the Moho depth,geophysical field,igneous rocks and historical earthquake records,and in Harbin the magnetotelluric sounding,drilling and mercury vapor survey were carried out.The research results show that the crust structure in Harbin is continuous,complete and stable,and earthquake activities of more than moderate intensity will not occur.
