谈拱涵开裂防治技术

On prevention technique of cracks on arch culvert

介绍了拱涵开裂的部位及形式,结合实际工程实例,阐述了裂缝的处治措施,并从基底加固处理、减少斜交角度、土方对称填筑、沉降缝防水处理四方面,对拱涵开裂采取的处治措施进行了探讨,从而杜绝二次病害的发生。

The paper introduces the parts and forms of the cracks in the arch culvert, illustrates the treatment of the cracks by combining with the factual engineering cases, and explores the treatment for the culvert cracks from the consolidation treatment of the base, reduction of skew angles, earthwork symmetric filling, and waterproof treatment of the settlement joints, in order to prevent two diseases.
