大连市西中岛起步区3号排洪渠地基处理分析

Analysis on the foundation treatment of No.3 flood discharge canal in Dalian Xizhong Island starting area

大连市西中岛起步区3号排洪渠主渠0+150~0+917.71段,承载力低,工程特性指标差,采用强夯置换法对渠道左、右两侧素填土和冲填土地基进行加固处理;主渠2+375.32~2+934.96段,堤身抗滑稳定不满足规范要求,采用强夯法对渠道和左、右岸堤身地基进行加固处理。分段采取不同地基处理方法对类似工程可提供一些借鉴。

Section 0 ＋ 150 -0 ＋ 917.71 of main canal of No. 3 flood discharge canal in Dalian Xizhong Island starting area is characterized by low bearing capacity and poor engineering property index. Dynamic compaction replacement method is applied for reinforcement treatment on plain fill and dredger fill foundations on the left side and right side of the canal. The skid resistance stability of the dyke body does not meet requirements in the specification in main canal section 2 ＋ 375.32 2 ＋ 934.96. Dynamic compaction replacement method is applied for reinforcement treatment on the dyke body foundations in the canal as well as the left and right banks. Different foundation treatment methods are applied in different sections can provide some references for similar projects.
