【摘要】 疏桩基础在上海已有五十年以上的历史,在温州亦有试点工程。但目前尚无实用可行的沉降计算方法。本文根据桩土变形协调关系,提出疏桩基础沉降计算的二元联立方程组。并通过几个工程实例,说明这一计算方法的可靠性。最后,对疏桩基础的应用和经济性作一初步探讨。更多还原

【Abstract】 The sparse piled foundation has been adopted in Shanghai for more than fifty years. Some testing projects also have been finished at Wenzhou. But, there is a need of practical method for the calculation of their settlements. Through the coordinate deformation between soil and piles, this paper suggests that the dualistic simultaneous equations are used in solving the settlement for the sparse piled foundation. In the paper some finished project examples are to express the reliability of this method. Finally, the application and economy of sparse piled foundation are discussed.更多还原
