摘要
针对钻扩灌注桩的基本原理和特征,结合实例进行扼要简绍。为了便于承载力的对比,分别选用6根钻扩灌注桩和6根钻孔灌注桩,且竖向、水平静载荷试验均为3根,分析其静载荷试验结果,探讨该桩型的发展方向和应用范围,进一步研究提高钻扩灌注桩单桩竖向承载力和水平承载力的问题,以达到降低工程投资、提高施工质量和保护环境的目的,供设计人员参考。
The piling technological coefficients of prestressed concrete pipe piles are closely related to their bearing properties and bearing capacity.Based on the piling technology of pipe pile and static load test results,the principles that should be taken into account in the design and calculation of the bearing capacity of prestressed concrete pipe piles were elaborated.In order to ensure the safety of the building,the piling pile technological coefficient,bearing properties,and bearing capacity of prestressed concrete pipe piles were discussed for the reference of designers.
