关于沉井的设计与施工研究

摘要

介绍了沉井的基本类型及组成部分，分析了沉井尺寸、系数验算、结构及刃脚的设计方法，从场地清理、沉井制作、垫木撤除、下沉施工等方面阐述了沉井的施工技术，对沉井技术的推广有促进作用。%The paper introduces the basic types and components for the open caisson, analyzes the design method for caisson size, calculation of coefficient, structure and cutting curb, and illustrates its construction technique from the site cleaning, caisson manufacturing, demolition of sole timber, and sinking construction, so as to enhance the extension of the caisson technique.
