摘　　要：勘察钻孔深度的确定,需要考虑诸多因素,具有一定的风险性。孔深的准确性、合理性对勘察工程的整体质量以及后期设计和施工质量、造价均有影响。尤其对于种类繁多的市政工程,如何保证孔深的有效性和针对性更是勘察工作的难点和重点。该文将通过工程经验、规范要求,结合工程实例,采取最不利思维和动态设计思路,多维度对勘察钻孔深度确定以及优化提出思路和方法,提高勘察工程质量,对综合市政工程勘察孔深确定有一定的借鉴意义。It is necessary to consider many factors to determine the depth of exploration drill,which has certain risks.The accuracy and rationality of the hole depth have an impact on the overall quality of the survey project,the quality of the later design and construction,and the cost.Especially for a wide variety of municipal projects,how to ensure the effectiveness and pertinence of the hole depth is the difficulty and focus of the survey work.Based on engineering experience,standard requirements and engineering examples,this paper will adopt the most unfavorable thinking and dynamic design ideas,and put forward ideas and methods for the determination and optimization of drilling depth in multiple dimensions.This study has certain reference significance for improving the quality of survey engineering and determining the depth of survey hole in comprehensive municipal engineering.
