Measures and techniques for dealing with road slippage on soft soil foundation
Quality accidents such as roadbed cracking or landslides often occur when filling soft soil foundation sections.In the the Pearl River Delta,the soft soil is widely distributed,and there are many fish ponds,which brings great difficulties to the subgrade construction.Usually,the design scheme of subgrade filling after soft foundation treatment is adopted.Filling the subgrade directly without soft foundation treatment will cause many diseases.This article takes the example of a landslide that occurred during the construction of a temporary road in a project in Zhuhai,Guangdong Province,passing through a fishpond section.In order to ensure the goal of opening to traffic,comprehensive measures such as"back pressure,load reduction,and surface stabilization"were taken to treat the landslide section,ensuring the stability of the roadbed,accelerating the treatment progress,and achieving the goal of opening to traffic.This provides a good idea for roadbed construction technology and roadbed disease treatment under special geological conditions of soft soil.
