在无覆盖层海床上修建钢栈桥,使钢管桩直接插入岩层,这给钢栈桥的设计和施工带来难度,特别是在不发达国家,因工业基础落后,施工设备缺泛,对这一技术的研究就显得更有必要。
The construction of a steel trestle on a seafloor without cover and the direct insertion of the steel pipe pile into the rock layer make it difficult to design and construct the steel trestle. Especially in the underdeveloped countries, because of the backward industrial base and the lack of construction equipment, Technical research is even more necessary.
