摘要
在当前国际电力工程中,越来越多的项目要求采用美国标准进行勘察设计。本文介绍了采用美国标准及相关手册计算单桩承载力的方法,评价了该方法与中国标准的区别及各计算参数取值问题。并将该方法应用于巴基斯坦某燃机电厂工程,采用国际通用的勘察及试验方法,结合获得的岩土参数进行了单桩承载力计算及群桩系数的讨论,并与现场静载试验结果进行比对。结果表明该理论计算方法理论清晰、计算结果可信,可作为相似国际工程的参考。
American standards are adopted in more and more international power projects to investigation and design. American standards and the reference manual concerning pile capacity calculation method are introduced. The difference between American and Chinese standards is reviewed, the value of design parameters are discussed. This method is applied in a CCPP project in Pakistan. The soil parameters are obtained according to American standards, then typical piles bearing capacity is calculated and such results are verified by static loading test. This study shows that the theory is clearer and the results are reliable. The study could be referred for the similar international projects.
