悬臂式和扶壁式挡土墙施工技术

Cantilever and CounterfortRetainingWallConstruction Technology

随着公路建设事业的发展,尤其是高等级公路的快速发展,传统的重力式挡土墙已不能满足公路建设的需求。悬臂式和扶壁式挡土墙在国外应用非常广泛,在我国随着高等级公路建设的推进也开始大量应用,尤其在缺乏石料地区和承载能力较低的地段比较经济。以溧水至马鞍山高速公路(江苏段)悬臂式和扶壁式挡土墙为工程实例,简要阐述其施工技术,为以后同类工程的施工积累了实践经验。

With the development of highway construction,especially the rapid development of high-grade highway,the traditional gravity retaining wall has been not able to satisfy the demand of highway construction.The cantilever and counterfort retaining wall is very widely used in the foreign countries,and is also started to greatly use with the construction of high-grade highways,and is more economic especially in the areas being short of aggregated rock and the sections with the lower carrying capacity.According to the engineering case of cantilever and counterfort retaining wall in Lishui – Maanshan Expressway(Jiangsu Section),the article briefly sets forth its construction technology in order to accumulate the practical experience for the construction of the similar projects.
