1 Introduction The Liujiahe Roller Dam project is located in the upper reaches of Liujia River in Yao County, Shanxian County. The control basin above the dam covers an area of 20km ~ 2. The design standard is once every 20 years and the corresponding maximum flood peak flow is 372m ~ 3 / s. The project is mainly composed of dam and concrete Permeable wall, right bank slope protection and steep slope, the dam is a masonry overflow gravity dam with a length of 110.8m, of which the overflow section is 46m long and the maximum dam height is 8.5m. The project has a maximum surface area of 25,000 and a storage capacity of 70,000 m ~ 3. It is a small-scale water conservancy project. The construction of this project is of great significance to the prevention and control of soil and water loss,
