摘要
文中根据工程区地质条件,共设计了三种基础方案,再通过混凝土用量筛选、成孔效率筛选及承台设计筛选得出大直径桩具有相对更优的适用性,因此,选择方案三更为适宜。通过低应变反射波法和静载试验得出两根桩均满足承载力要求,但桩身完整性存在一定不足,尤其16^(#)桩的桩身、桩底不足较显著,后续施工应切实注意施工安全和质量。
Based on the geological conditions of the engineering area,three basic schemes were designed in this article.Through the screening of concrete dosage,pore forming efficiency,and bearing platform design,it was concluded that large-diameter piles have relatively better applicability.Therefore,the selection of scheme three is more suitable.Through the low strain reflected wave method and static load test,it was found that two piles meet the bearing capacity requirements,but there are certain deficiencies in the integrity of the pile body,especially the significant deficiencies in the pile body and bottom of pile 16.Subsequent construction should pay attention to construction quality.
