增加桩基承载力的理论研究

Theoretical Research on Improving the Bearing Capacity of Pile Foundation

根据中华人民共和国国家标准GB50007-2002建筑地基基础设计规范中给出的计算单桩竖向承载力特征值的计算公式[1],并结合工程实践,建立相应的优化模型,同时,用多目标遗传算法进行求解,在理论上论述了增大桩基承载力的方法.该方法对实践工作很有指导意义,若能在实践中找出实施方法,将会产生很大的经济效益.

The computational formula for the eigenvalue of the vertical bearing capacity of individual pile according to the national standard GB50007-2002 was presented.The optimal mathematical model with the multi-objective genetic algorithm was solved and the method of improving the bearing capacity of pile foundation theoretically was gotten,which has important instruction meaning in practical work.It will bring out great economic benefit if it can be carried out in practice.
