摘要
沿海地区由于独特的地理、地质条件,分布着较多的河流,河道表层分布淤泥,其下孤石非常发育,地质条件复杂,加之孤石自上而下分布,分布面较广,加大了桥梁的施工难度。以国道G240线台山大江至那金段改扩建工程锦石大桥水中墩承台墩柱施工为对象,采用钢板桩围堰的施工方法,介绍施工过程中遇到的问题和解决措施。
Due to unique geographical and geological conditions,there are many rivers distributed in coastal areas.The surface layer of the river is distributed with silt,and the underlying boulders are very developed.The geological conditions are complex,and the distribution of boulders from top to bottom is wide,which increases the difficulty of bridge construction.This paper takes the construction of the water bearing platform and pier columns of the Jinshi Bridge in the renovation and expansion project of the Taishan Dajiang to Najin section of the National Highway G240 as the object.The construction method of steel sheet pile cofferdam is adopted,and the problems encountered during the construction process and solutions are introduced.
