摘要
Abstract
Due to the poor geological conditions of the slope of the tailrace channel of Yinjiang Hydropower Pro-ject and its close proximity to G353 National Highway,the excavation range of the slope is limited,and the part of the slope is made of silty sandy soil.After the operation of the project,the tailrace channel slope is partially underwater.Affected by the operating conditions,the water level of the slope fluctuates,and it also needs to bear the load of the slope fishway,which sets a variety of difficulties and complex conditions in one.In order to ensure the safety of the project,it was finally decided to adopt the"concrete panel+anchor reinforcement pile"support scheme.At present,the construction of the slope has been completed,and after about a year of safety monitoring,the monitoring data show that the slope has converged without deformation,which proves that the slope support scheme is reasonable.This paper describes the research process of the slope support scheme,aiming to provide reference for similar projects.关键词
