Abstract
In order to solve the safety problem of toe plate of concrete faced rockfill dam in reservoir,this paper takes a small reservoir project in Guizhou province as an example to analyze the design of toe plate of concrete faced rockfill dam in reservoir,and uses color Doppler ultra-sonic diagnosis instrument and total station to monitor the concrete strength,horizontal and vertical displacement of toe plate respectively.The practice shows that the average strength of toe slab concrete in 35 sampling points is 29.6 MPa,and the strength guarantee rate is 98.3%,which is higher than the design requirement.The maximum displacement in X direction and Y direction are 3 mm and 2.9 mm respectively,which are smaller than the pre-warning value of horizontal displacement 3.5 mm,indicating that the reservoir has excellent anti-seepage per-formance.关键词
