河道中停车平台建设对河底供水管道的影响性分析

Analysis on the influence of parking platform construction in riverway for river bottom water supply pipeline

本文利用有限元软件,对沈阳市南运河河道底部的供水管道及周边结构进行了三维仿真模拟,针对河道左岸停车平台的建设对管道受力及位移情况的影响进行了研究分析。结果表明:河道左岸停车平台的建设会导致河底管道沉降增大21.5mm,管道的大主应力达到927.47k Pa,属于小变形、小应力的状态。因此,对河底供水管道的受力情况影响较小。

In the paper, finite element software is utilized for 3D virtual simulation on water supply pipeline and surrounding structure at the bottom of the Shenyang South Canal. The influence of river left bank parking platform construction on pipeline stress and displacement condition is studied and analyzed. The results show that fiver bottom pipeline settlement is increased by 21.5mm, the pipeline major stress reaches 927.47kPa due to the construction of river left bank parking platform. It belongs to small deformation and small stress state, thereby the construction has less influence on stress condition of fiver bottom power supply pipeline.
