【摘要】：为了分析尼泊尔地震中山区公路沿线自建民居的震害,在对加德满都-樟木口岸公路沿线民居震害调查的基础上,详细介绍了框架结构和砌体结构自建民居的特点,按照地震直接灾害和次生灾害,总结了这2种自建民居结构的震害特征,给出了其地震破坏比例.框架结构基本完好的比例是砌体结构的3倍多,而中等破坏、严重破坏和毁坏的比例约为砌体结构的1/2.根据震害调查和统计分析,得到以下结论:自建框架结构虽未经过正规设计,不满足尼泊尔建筑规范的相关要求,施工质量也比较欠缺,但破坏程度小于自建砌体结构;随公路海拔的升高,沿线民居的震害程度有加重的趋势;山区地震导致的次生灾害对沿线民居建筑的破坏比较严重.
[Abstract]:In order to analyze the earthquake damage of the self-built houses along the highway in the mountain area of Nepal earthquake, on the basis of the investigation of the earthquake damage along the Kathmandu-Zhangmu Port Highway, the characteristics of the self-built houses in the frame structure and the masonry structure are introduced in detail. According to the earthquake direct and secondary disasters, the earthquake damage characteristics of the two kinds of self-built residential structures are summarized, and the earthquake damage ratio is given. The ratio of the frame structure being basically intact is more than three times of that of the masonry structure, but the damage is moderate. The proportion of serious damage and destruction is about 1 / 2 of the masonry structure. According to the investigation of earthquake damage and statistical analysis, the following conclusions are drawn: although the self-built frame structure is not formally designed, it does not meet the relevant requirements of the Nepal Building Code. The construction quality is also short, but the damage degree is smaller than the self-built masonry structure; with the elevation of the highway, the earthquake damage degree of the residential buildings along the line has an aggravating trend; the secondary disaster caused by the mountain earthquake damage to the residential buildings along the line is more serious.
