摘要
为合理评价软土地区基坑的勘察质量,文中以P×C法为理论基础,开展基坑勘察质量风险源识别及分级评价,并结合变形监测成果来佐证分析结果的准确性。结果表明,基坑整体勘察质量得分为90.99分,其整体勘察质量等级为Ⅳ级,说明该项目的勘察质量很好,完全满足工程需要;同时,通过变形监测成果分析,得出基坑变形远小于设计要求的控制值,说明勘察为基坑支护设计提供的参数是正确的,侧面佐证了勘察质量评价的合理性。
To reasonably evaluate the survey quality of foundation pits in soft soil areas,this article takes P×Based on the C method,the identification and grading evaluation of quality risk sources in foundation pit exploration are carried out,and the accuracy of the analysis results is supported by deformation monitoring results.The analysis results show that through calculation,the overall survey quality score of the foundation pit is 90.99 points,which means its overall survey quality level is IV,indicating that the survey quality of the project is very good and can fully meet the engineering needs;Meanwhile,through the analysis of deformation monitoring results,it was found that the deformation of the foundation pit is far less than the control value required by the design,indicating that the parameters provided by the survey for the design of foundation pit support are correct,which indirectly supports the rationality of the quality evaluation of the survey.
