砂桩加固吹填饱和粉砂土的应用研究

STUDY ON THE APPLICATION OF SATURATED POWDER SAND ON THE WEAK FOUNDATION REINFORCED BY SAND PILES

本研究分析了饱和砂土的特性及危害,提出了利用砂桩、生石灰块加固饱和 砂土作为地基的可能性,进行了饲料车间地基处理与加固设计和施工。经过了对加固桩 加载试验和实测,证明了采用砂桩和生石灰块桩加固软弱地基的设计方案是成功的,不 仅经济造价低,而且建筑物稳定安全。

The possibility of utilization of saturated sand on the weak and soft foundation reinforced by sand piles and bulks of quick lime is studied on the basis of analysing the properties and harm-fulness of saturated sand. The foundation of a feed workshop has been designed and constructed by reinforcement method. The loading experiment of reinforcing piles and pratical measurments show that the design of reinforcing the soft and weak foundation by sand piles and bulks of quick lime is successful, not only the construction cost is low,but also the building is stable and safe.
