中印地铁工程混凝土结构设计比较

A Comparison of Concrete Structure Design of Sino-India Metro Engineering

对印度地铁工程中混凝土结构设计规范的应用进行分析,并就基础理论、工程材料、荷载组合、极限状态、抗震分析、构造要求等方面与我国规范进行了对比。印度与我国的混凝土结构设计理论均采用以概率理论为基础的极限状态设计法,但由于不同的安全储备度和经济性选择,具体的工程应用中与我国规范相比还是有一定的差异性:印度材料设计强度高于我国以及裂缝计算公式不同,地下结构裂缝一般不控制配筋,正截面设计较我国经济,但其斜截面抗剪要求较高。

The application of concrete structure design standard is made an analysis for India metro engineering in this paper,and then,a comparison of Sino-India standards is done focusing on foundation theory,engineering material,load combination,ultimate state design analysis,anti-seismic analysis and structure requirements,etc.Concrete structure design theory in India uses ultimate state design based on probability theory,and it is similar with China.But there exists certain difference of detailed project application compared with Chinese standard due to different safety storage degree and economy property choice.The detailed differences are summarized as follows: the material design strength of India is higher than that of China with different crack calculation formula;underground structure crack will not control distributed steel generally;section design in India will be more economic than that in China,but curved section has higher shear requirements.
