软土地层超深地连墙槽壁失稳及控制措施研究
Study on Trench Wall Instability and Control Measures of Extra-Deep Diaphragm Wall in Soft Soil Layer
摘要
Abstract
The subway station in a coastal city is located in soft soil,the diaphragm wall is used as the enclosure structure.The trench wall is unstable in the construction process.In this paper,the causes of trench wall insta-bility are analyzed and a series of measures are taken.The results show that the ratio of wall protective mud and the time of trench formation are the main factors affecting the stability;the extra-deep diaphragm wall,needs to comprehensive analysis from the slotting time,the weight of the steel cage and other aspects to decide the fram-ing design;for L-shape and Z-shape and other special amplitude diaphragm wall,the use of the three-axis mixing pile to reinforcement the trench wall,can greatly improve the stability of trench wall and ensure the safe-ty of engineering construction.关键词
