摘要:
为改善我国下穿立交积水现状,提出在排水系统中增加储水管道的设计方案.基于交通荷载作用下的管–土力学模型,建立储水管道仿真模型,并采用有限元方法分析该仿真模型,对储水管道进行配筋验算,同时分析储水管道各参数对其力学特性的影响.研究结果表明:该仿真模型是可行的;储水管道埋土深度﹑土基模量﹑管壁厚度﹑管道直径等管道参数对其力学特性影响显著.结合研究结果,推荐储水管道埋土深度1.5 m,底部土基模量40 MPa,管壁厚度10 cm,管道直径1 200 mm.
Abstract:
In order to improve the present waterlogging condition of underpass,a scheme of adding a storagepipe in underpass is given.Based on the tube-soil mechanics model,a simulation mechanical model of storagepipe is built,which is analyzed by finite element method. The reinforcement of the storage pipe is calculated,while the influence of parameters on the mechanical property of storage pipe is studied. The test results showthat: the covering earth thickness,the soil base modulus,the wall thickness and the diameter have significantinfluence on mechanical property of storage pipe. According to the research results, a new storage pipe is rec-ommended as follows: covering earth thickness of 1.5 m, soil base modulus of 40 MPa,wall thickness of 10cm and diameter of 1200 mm.
