振冲碎石桩工程质量因素的试验研究

Pilot Research on the Factors Affecting the Vibration Crushed Stone Project's Quality

分析了影响振冲碎石桩质量的因素。通过正交试验,分析了桩径、桩长、碎石垫层对振冲碎石桩承载性能的影响,说明了碎石垫层的必要性、小桩径的合理性和有效桩长的经济性。

In this paper the factors which affect the the vibration crushed stone piles＇Quality are analysized. By orthogonal test, the effects of the diameters and lengths of the piles and the crushed belting course on the bearing performance of the vibration crushed stone piles are analysized;the necessity of the crushed stone belting course, the rationality of the small radius and the economical characteristics of the effective pile lengths are explained as well.
