随着我国桥梁建设的发展,在深水桥墩中采用大型管柱基础已日见普遍。管柱下端锚固在岩床内,由于岩面不平整,往往在同一桥墩中各根管柱下端锚固点标高亦不一致。因此,即使管柱在平面上系对称布置,由于各根管柱计算长度不同,整个承台仍然是不对称的。近年来,对于仅 With the development of the bridge construction in our country, it has become more and more common to adopt the large-scale pipe string foundation in the deep-water pier. The lower end of the pipe string is anchored in the rock bed. Due to the uneven rock surface, the elevation of the anchorage point at the lower end of each pipe string in the same pier is also not consistent. Therefore, even though the pipe strings are symmetrically arranged in a plane, the entire caps are still asymmetrical due to the different calculated lengths of the pipe strings. In recent years, for only
