| Abstract: | 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. |
