随着山区交通事业的发展 ,对地质环境的破坏加剧 ,地质灾害发生频率增加。其中突发性的山体崩塌往往造成车毁人亡的恶性事故。作者通过对今春发生在“丽浦公路”和“金温铁路”线上的两起山体崩塌实地考察和背景资料分析 ,初步得出 :区域地质构造复杂、多组断层交汇和刚性的地层岩性 ,是山体崩塌的地质基础 ;建设施工破坏边坡和降雨 ,是山体崩塌的诱发因子。最后提出 ,在交通设计、施工和验收中必须加强防患地质灾害 ,进行地质环境质量评价
With the development of transportation in the mountains, the damage to the geological environment is aggravated, and the frequency of geological disasters increases. One of the sudden mountain collapse often caused by car crash of the vicious accident. Based on the field investigation and background data analysis of two mountain collapses occurred on the lines of “Liupo Highway” and “Jin-Wen Railway” in the spring of this spring, the author initially concludes that the geological structure of the region is complicated, the interlacing of multiple faults and the rigid lithology , Is the geological basis of mountain collapse; construction and destruction of the slope and rainfall, is the trigger of mountain collapse. Finally, it is suggested that geological disasters should be strengthened in traffic design, construction and acceptance to evaluate the quality of geological environment
