城市道路路面塌陷成因初探

Discussion on the causes of city road section collapses

分析总结了城市道路路面塌陷的塌陷深度、塌陷时间分布和周围环境等特点,研究了地下水位变化、冻融、公路施工质量、水管渗漏、车辆超载、地下工程施工等因素引起路面塌陷的形成原因和过程,为研究路面塌陷灾害的治理研究提供借鉴。

This paper analyzed and summarized the collapse depth, collapse time distribution and surrounding environment and other characteris- tics of city road section collapses, researched the formation causes and process of road section collapses caused by underground water level change, freezing thawing, highway construction quality, conduit leakage, vehicles overloading, underground engineering construction and other factors, provided reference for the treatment of road section collapses disasters.
