近年来我国国民经济快速发展，桥梁建设规模不断扩大，砌石重力式U型桥台因其构造简单、造价低、取材容易，成为一种广泛采用的桥台型式，实际工程中发现该种型式桥台侧墙开裂显现也较为普遍。本文以砌石重力式U型桥台侧墙开裂的实际工程为例，对桥台台后填土种类、干湿密度、含水量、内摩擦角、粘聚力等参数进行了详细地检测分析，并结合桥梁的交通状况、环境因素、受力特点等因素对裂缝的成因进行了深入分析，最后给出了相应的加固措施。

In recent years, with the rapid development of China's economy and the expanding bridge construction, masonry gravity U-shaped abutments become a widely used type because of its simple structure, low cost, easy drawn. However, in the actual project this type of abutment is found sidewal cracking more common. In this paper, regarding the masonry gravity U-shaped abutment sidewal cracks in actual project as an example, analyzed and detected abutment backfil species, wet and dry density, moisture content, angle of internal friction, cohesion and other parameters in detail. Combine with the bridge traffic conditions, environmental factors, mechanical characteristics and other factors, analyzed the causes of cracks in-depth. Final y, the corresponding reinforcement measures are given.
