摘要

摘要: 通过实地考察, 对2014年5月30日9时20分云南省德宏傣族景颇族自治州发生的6.1级地震中的房屋震害特点及主要次生地质灾害特征进行了全面分析, 并初步总结了各类房屋建筑及主要地质灾害的震害特征及其成因。研究结果表明, 对于西南山区类似盈江的地震多发区带, 城镇建设过程中在尽量选择高强度建筑材料且保证建筑材料合格的同时, 还要充分重视科学选址, 应尽量避开滑坡、崩塌、泥石流等地震地质灾害易发地带; 对稳定性较差的场地应通过必要的地基处理工程进行加固, 以尽可能减小地震造成的破坏; 在易发生地质灾害的道路周边还应采取适当的加固措施以避免地震来临时造成交通瘫痪, 进而引发更大的生命财产损失。

Abstract: The M_s 6.1 earthquake occurred in Dehong Dai and Jingpo autonomous prefecture in Yunnan province on May 30 nine twenty, a large number of civil building destruction. This paper comprehensively analyzes the characteristics of building damage caused by the earthquake and the main secondary geological disasters by the means of on-the-spot investigation and visit. At the same time, this paper preliminarily summarizes their causes and all kinds of damage characteristics of building caused by earthquake and the characteristics of main geological disasters. The results show that in the southwest mountainous earthquake prone area which is similar to Yingjiang, the urban constructions not only need to choose high strength building materials and ensure architecture qualifications, but also pay close attention to scientific location, try to avoid the earthquake and geological disasters prone zone such as the landslide, collapse, debris flow and others. To minimize the potential earthquake damage, poor stability field should be reinforced by means of some necessary foundation treatments engineering. The geological disasters are likely to occur around the road should also take proper reinforcements to avoid the earthquake causing traffic gridlock, and greater loss of life and property.
