引江济淮工程舒庐干渠渡槽充水试验应力应变成果分析

Analysis of Stress and Strain Results of Water Filling Test of Shulu Main Canal Aqueduct of River Diversion to Huaihe Project

为验证新建水工渡槽承载能力,对引江济淮工程舒庐干渠渡槽进行充水试验,并采用有限元方法对试验全过程进行仿真分析,将各工况下的应变(应力)理论计算结果与现场实测数据进行对比分析,得出两者之间的相关性,最后依据公路桥梁荷载试验规程及试验成果,判断结构处于弹性工作状态,刚度满足设计要求,可为类似工程提供一定的参考依据。

In order to verify the bearing capacity of the newly built hydraulic aqueduct,a water filling test was carried out on the Shulu main canal aqueduct of the Yangtze River to Huaihe River project.And the finite element method is used to simulate and analyze the whole process of the test.The theoretical calculation results of strain(stress)under each working condition are compared and analyzed with the field measured data,and the correlation between the two is obtained.Finally,according to the highway bridge load test regulations and test results,it is judged that the structure is in an elastic working state,and the stiffness meets the design requirements.It can provide a certain reference basis for similar projects.
