| 摘 要： | 2013年12月1日新疆柯坪县发生M5.3地震,柯坪县境内震感强烈,极震区烈度为Ⅵ度。综合分析余震分布和震源机制解,确定本次地震的发震构造为柯坪推覆构造最南端的柯坪塔格断褶带。对灾区乡镇进行房屋调查,土木结构房屋破坏最严重,砖木和砖混结构房屋基本无破坏。该地区为盐渍土发育,地下水埋藏较浅,对地震破坏有放大效应,加大了地震的震害损失。

| Abstract: | There was a M5.3 earthquake in Kalpin, Xinjiang, China, on December 1, 2013.The alluvial plain tilt is distributed in the south of Kalpin country.The soil is mainly sandy and has silty fine particles.Due to shallow groundwater, there is plentiful saline soil.A series of low mountains and banded depressions are distributed in the north of Kalpin country.This earthquake was located in the southwestern part of Tianshan.There is a part of Kalpin thrust tectonic system that belongs to the edge of the Tarim basin.The Kalpin thrust tectonic system is an important part of the foreland thrust tectonic of the south Tianshan.This thrust tectonic system consists of a series of north-dipping imbricate thrusts.The slip plane of the thrust fault belongs to the Cambrian system.The Kalpin M5.3 earthquake occurred in Kalpintag fault fold, which belongs to the south Kalpin thrust tectonic system.The reasons of the loss in this earthquake are twofold.First, there are many old houses and self-built houses with low seismic capacity, and some old dwellings belong to building, which were already dilapidated before the earthquake.Second, the groundwater level is low and the soil is saline, so the foundation is bad.This saline soil has an amplification effect on earthquakes, and under synthetic action the housing experienced considerable damage during this earthquake. |
