砌石重力式U型桥台侧墙裂缝成因分析

The cause analysis of sidewall cracks in masonry gravity U-shaped abutments

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深入分析,最后给出相应加固措施。

In this paper, taking the masonry gravity U -shaped abutment sidewall cracks in actual project as an example, analyzed and detected abutment backfill species, wet and dry density, moisture content, angle of internal friction, cohesion and other parameters in detail.Combined with the bridge traffic conditions, environmental factors, mechanical characteristics and other factors, analyzed the causes of cracks in -depth. Finally, the corresponding reinforcement measures are given out.
