城市粉土地面塌陷的影响因素分析及成因研究

粉土作为一种具有特殊性质的土,自身的粉粒含量很高,当粉土处于饱和状态下就容易发生土颗粒随水流动的现象,进而对地面的建(构)筑物造成较大的危害。文章以城市粉土地面塌陷为研究对象,重点研究降水下渗、地下管线渗漏和市政工程施工对地面塌陷的影响,分析其不同的致灾机理,进而提出相应的城市地面塌陷防治措施。该研究可以为城市粉土地面塌陷和相关地质灾害的预防,提供科学理论和依据。

Silt,as a kind of soil with special properties,has a high content of silt.When silt is saturated,it is easy to flow with water,which causes great harm to the buildings on the ground.This paper takes the urban silt ground collapse as the research object,focuses on the effects of precipitation infiltration,underground pipeline leakage and municipal engineering construction on ground collapse,analyzes their different disaster mechanisms,and then puts forward the corresponding prevention and control measures of urban ground collapse.This study can provide scientific theory and basis for the prevention of urban silt ground collapse and related geological disasters.
