Abstract
This paper mainly studies the foundation treatment method of upstream concrete cofferdam.By es-tablishing a three-dimensional finite element model,the distribution of stress at the foundation of the concrete cofferdam was analyzed by using the frame-type jet grouting continuous wall foundation treatment method and the jet grouting continuous wall pile foundation replacement method.The results show that both the frame-type jet grouting continuous wall foundation treatment method and the jet grouting continuous wall pile foun-dation replacement method can share most of the stress of the concrete cofferdam bottom to satisfy the bearing capacity of foundation,but the frame-type jet grouting continuous wall foundation treatment method will cause large uneven foundation settlement.Through the calculation and actual operation,it is found that the jet grou-ting continuous wall pile foundation replacement method is more effective to solve the foundation treatment problem on the soft overburden.关键词
