摘要
金泽水库取水闸基础底部有深厚软塑状粉质黏土土层,易产生较大的沉降变形。取水闸天然地基基础用同济启明星和通用三维沉降计算软件进行最终沉降量比较计算,结果不满足沉降控制要求。取水闸基础处理多种方案进行比选和优化设计,结合工程实际情况选用钢筋混凝土预制方桩,并优化桩基础布置方案,有效减小了最终沉降量并满足规范要求。
The bottom of water intake gate foundation of Jinze reservoir has a deep soft plastic silty clay layer,which may result in large settlement deformation.The final settlements of natural foundation of water intake gate are compared and calculated by using the Tongji Qimingxing software and the general three-dimensional settlement calculation software,however,the results do not meet the requirements of settlement control.The paper introduces the selection and optimization design for the multiple treatment schemes of water intake gate foundation,describes the selection of reinforced concrete precast square piles and the optimization of pile foundation layout scheme combining with the actual project situation,then the final settlement is effectively reduced and meets the specification requirements.
