摘要
软基是一种非常常见的地质状态,通常由于设计及施工不重视会引起质量问题。根据工程施工时间紧、场地狭窄、不能影响已建成码头的的桩基、地质指标不适合大型机械等特点,对软基处理的方式(钻孔灌注桩)、施工中的质量控制及所采用的整体稳定性计算方法(强度折减法)进行了探讨。工程使用半年多来证明,施工质量控制、方案与计算校核方法的选择对工程保质、按时使用起到了很好的保证作用,为软基采用钻孔灌注桩并对其整体稳定性的计算提供借鉴。
Soft foundation is a very common geologic state,on which quality problems often occur due to improper design and construction.Since the construction time and yard are limited,in order not to affect the pile foundation of the existing wharf under the geologic condition which is not suitable for the large-scale machine,we carry out a research on the method of soft foundation treatment（bore-hole poured piles）,quality control during construction,as well as the integral stability calculation method which is adopted in the project.The operation of more than half a year proves that the construction quality control and the choice of scheme and check method has guaranteed the smooth completion and putting into operation of the project.It may serve as references for the application and calculation of bore-hole poured piles for the soft foundation.
