重庆某码头混凝土立柱裂缝的治理
|
摘要
某码头工程立柱出现裂缝,由护岸填方的侧向作用引起。裂缝宽度已超过国家规范要求,所以对立柱结构进行了修补。通过此类问题分析,提出在高填方区的立柱,设计应考虑的相关因素和施工应采取的相应措施,使之在承受阶段性侧向作用时,安全性和耐火性不受影响。
The concrete column cracks in certain wharf engineering were caused by the lateral action of embankment, and the crack width ex- ceeded the requirement of national specification, so it is necessary to repair the column. Through the analysis of this kind of problem, the author proposed that the designer must consider the related factors and corresponding measures for the columns in high filling region to ensure the safety and fire resistance under staged lateral action.
