摘要
为了研究江西省近年来致死性地质灾害发育规律,利用2013～2022年江西省致死性地质灾害调查资料,采用统计分析方法,研究了 45起致死性地质灾害发育特征及其承灾体特征.江西省地质灾害具有规模小、数量多、危害大、多由暴雨引发的特点;地质灾害多发育于土质斜坡中,工程切坡是地质灾害的重要引发因素;致死性地质灾害造成房屋全毁的少,多数情况下仅造成房屋后墙倒塌或局部受损;个人能力在躲避地质灾害时的作用不明显;睡眠状态时受灾人员最容易死亡,房屋局部受损就可能造成人员死亡.
Abstract
In order to study the development law of lethal geological disasters in Jiangxi Province in recent years,the development characteristics of 45 lethal geological disasters and the characteristics of their bearing bodies were studied by using the survey data of lethal geological disasters in Jiangxi Province from 2013 to 2022 and statistical analysis methods.The geological disasters in Jiangxi Province are characterized by small scale,large quantity,great harm and rainstorm;Geological hazards are mostly developed in soil slopes,and engineering slope cutting is an important triggering factor of geological hazards;Geological disasters rarely cause total damage to houses,and in most cases only cause back wall collapse or partial damage;The role of personal ability in avoiding geological disasters is not obvious;The victims are most likely to die when they sleep,and local damage to the house may cause death.
