摘要
随着我国交通建设规模的不断扩大,隧道里程、数量不断提升,隧道坍塌事故时有发生,对隧道工程和施工人员产生重大威胁。因此,明确隧道坍塌事故的时空特征,厘清其主要坍塌原因,对保障我国隧道工程建设,加速交通事业发展进程具有重要意义。该文通过搜集2006—2022年的隧道工程坍塌案例,对坍塌事故时空特征进行梳理,总结主要致害原因,并结合具体案例进行剖析,主要结论如下:隧道坍塌事故主要发生在下半年的7、8、12月,应针对这些重要月份加强施工监管;事故发生次数最多的为广西,单次事故死亡人数排名前三的为甘肃、安徽和天津;高速公路隧道事故发生频率最高,死亡人数最多,其次是铁路隧道。隧道坍塌致害原因主要分为不良地质、设计及施工不当和其他自然原因。而隧道坍塌事故绝大多数源于多因素的综合作用。
With the continuous expansion of the scale of traffic construction in our country,the mileage and number of tunnels are increasing,and tunnel collapse accidents occur from time to time,which pose a major threat to tunnel engineering and construction personnel.Therefore,to clarify the time and space characteristics of tunnel collapse accidents and clarify the main causes of tunnel collapse are of great significance to ensure tunnel construction and accelerate the development of transportation in our country.This article collects tower defense cases of tunnel engineering from 2006 to 2022,this paperanalyzes the temporal and spatial characteristics of the collapse accident,summarizes the main causes,and analyzes the specific cases.The main conclusions are as follows.Tunnel collapse accidents mainly occur in July,August and December in the second half of the year,construction supervision should be strengthened for these important months;Guangxi has the largest number of single accidents,and Gansu,Anhui and Tianjin are the top three fatalities;highway tunnel accidents have the highest frequency and the largest number of deaths,followed by railway tunnels.The causes of tunnel collapse are mainly divided into bad geology,improper design and construction and other natural causes.Most of the tunnel collapse accidents are caused by the comprehensive action of many factors.
