川西地区井架基础软弱地基处理方法探讨

The investigation of soft ground approach about the wellsite derrick foundation in western Sichuan

通过对川西地区不同软弱地基地质条件分析,采用换填处理、桩基础、钢筋筏板基础三种地基处理方法一般都能满足要求。经济性评价表明,对不同厚度的软弱地基,三种方法适宜性不同,钢筋筏板基础具有施工方便、快捷、费用较低等特点,在川西地区原状土软弱地基处理中具有较好的应用价值。

Through the analysis of the geological conditions of different soft ground in western Sichuan,replacement treatment,pile foundation,reinforced raft foundation generally can meet the requirements of the foundation treatment.Economic evaluation shows that three methods are different in suitability in soft ground for different thickness.Reinforced raft foundation construction is convenient,fast,and lower cost,better value in the western Sichuan region undisturbed soil soft ground treatment.
