摘要
结合典型的工程地质特点及工程实例,论述了粉喷桩处理软土路基沉降的计算方法,提出在进行沉降分析和沉降控制的基础上,对软土路基处理的设计方案进行分析和选择,特别是探讨了桩长和桩间距的选择等问题,对不同设计方案在沉降控制等方面进行分析和比较,得到了一些对工程实际十分有益的结论,对于用粉喷桩处理桥头路基防治跳车等问题有直接的指导意义。
Combinating the typical engineering geology characteristics and the typical example, the method of calculating settlement of, handling the soft soil roadbed by DJM piles are discussed; and on the basis of settlement control and analysis, the project of design use DJM pile to handle soft soil roadbed was chose optimally, especially the pile length choice and pile distance choice are discussed. And the different design schemes based on settlement control were analyzed and compared; some physically and very beneficial conclusion are drawn for using DJM piles to handle the bridge head roadbed and curing the automobile bouncing on either end of bridge etc.; and they have the direct leading meaning.
