【摘要】 黄壁庄水库除险加固拟在主坝与位于离主坝顶100m左右水库内的原有灵正渠首之间架设一座深水桥梁。该桥施工最大难度是大跨度深水施工支护。以已成桥柱为基础的斜臂支撑的刚构支护结构,较好地解决了深水支护的困难。实践证明,采用此法支护能充分利用材料特性节约原材料,同时又加快施工进度,是一种解决高架施工支护的可行方法,可供同类工程参考。更多还原

【Abstract】 In Huangbizhuang reservoir reinforcement project, a deep water bridge will be built between the main dam and the head of the old Lingzheng trench, which is about 100 meter to the top of the main dam. Long-span deep water timbering is the most difficult problem for construction of the bridge. An oblique arm supporting rigid frame timbering based on the built bridge columns better to solve the difficult deep water timbering problem. By this method, it not only can sufficiently make use of materials’ properties to save raw materials, but also quicken the construction process. It has been proved in practice a feasible method to deal with the viaduct bridge construction timbering, and can be used by other same kind of projects.更多还原
