杭州湾大桥补充定额分析与确定

杭州湾大桥在设计施工中采用了70m混凝土箱梁整孔运输一体化、大直径超长钢管桩制造施打、移动模架洗注50m箱粱等新技术，采用这些新技术的分项工程所占投资比例大。因此，分析与确定这些分项工程的工料机消耗量，编制科学的补充定额，可合理确定工程造价，并为同类工程提供借鉴。

Analysis and determination of additional norms for Hangzhou Wan major bridge

For Hangzhou Wan major bridge are employed such new techniques as system integration of transporting full 70m concrete box girder spans and the fabrication, construction and driving of extra-long steel tubular piles of major diameter as well as casting of 50m box girders in traveling formwork. Partial works exploiting the above- mentioned techniques make up a large percentage of the investment. The analysis and determination of the consumption of labor, materials and machines of the partial works and the preparation of scientific additional norms can rationally determine the engineering cost and provide reference to projects of a similar nature.
