摘要
京沪高速铁路跨越津静公路的连续梁桥水中承台施工中,尝试采用I36b工字钢插打而成的"钢板桩围堰",介绍了钢围堰结构构造型式、设计计算、主要施工技术及施工注意事项,通过实践取得了较好的效果。实践证明,型钢"钢板桩围堰"适用于基坑开挖不深、粘性土层、地下水不丰富的华北大平原及西北黄土高原地区。
During the construction of the bearing platforms of the Beijing-Shanghai high-speed railway continuous bridge crossing the Jin-Jing Highway, type-136b I steels were trial-assembled into steel-pile cofferdam for the construction, the structural forms of, and design calculations and main construction techniques for, and the main points for attention during the construction of which are dealt with in detail in the paper. The steel-plate cofferdam has resulted in very good effects in practice. It is found applicable to lower foundation pits, clay soil, and water-lacking areas, such as the North China Plain and North-west Highland.
