摘要
为了研究新建预制检查井的受力特征及施工优化措施,以某实际工程为背景,根据预制检查井现场调查及室内混凝土试验结果,通过有限元abaqus软件建立4种井深数值模型,研究了不同深度预制检查井的最大主应力、最小主应力的受力特征,并提出了施工优化措施,在市政管网建设中成功实施。
Based on an actual project,this paper studies the stress characteristics and construction optimization measures of new prefabricated inspection wells.According to field investigation of prefabricated inspection wells and indoor concrete test results,four numerical models of well depth are established by using finite element ABAQUS software.The stress characteristics of maximum and minimum principal stresses of prefabricated inspection wells with different depths are studied,and construction optimization measures are put forward,which are successfully implemented in municipal pipeline network construction.
