挡土墙是用来防止土体坍塌、截断土坡延伸的土工构筑物,广泛应用于水利水电、公路、铁路、桥梁、房屋、矿山、码头等工程建设中。比如基坑开挖支护,地下建筑物边墙,路堤、路堑护墙,桥台,河道两岸的护岸墙,边坡挡土墙等都属于挡土构筑物。目前国内对于挡土墙的支护边坡抗震性能的研究却并不多。所以研究地震作用下,如何使挡土墙的抗震性能更好,具有非常重要的现实意义。 The retaining wall is a geotechnical structure used to prevent soil collapse and cut off the extension of the soil slope. It is widely used in the construction of water conservancy and hydropower, roads, railways, bridges, houses, mines, and docks. For example, excavation and support of foundation pits, the side walls of underground buildings, embankments, retaining walls, abutments, revetment walls on both banks of the river, retaining walls of slopes, etc., are all retaining structures. At present, there are not many studies on the seismic performance of retaining walls of retaining walls in China. Therefore, under the action of earthquake, how to make the retaining wall have better seismic performance has very important practical significance.
