动力固结法(也称强夯法)。就是从高处重复多次落下重锤、给地基以强大的冲击力和振动,使地基密实得到加固的方法,在进行动力固结法设计时,需决定如下参数: 锤重 W(吨);锤的落距 H(米); 捶击数 N(次/夯点);夯击遍数 n(遍); 夯点间距 I(米);休置时间 T(天); 平均夯击能量 E(吨·米/平方米) 其中锤重W、落距H和夯点间距I,预定加固深度D(米),用下式求得:
Dynamic consolidation method (also referred to as dynamic compaction method). It is a method of repeatedly dropping heavy hammers from high places and giving a strong impact force and vibration to the foundation to reinforce the foundation. When designing the dynamic consolidation method, the following parameters need to be determined: Hammer weight W (tons); Drop distance H (meters) of hammer; number of impacts N (times/points); number of strokes n (passes); distance between points I (meters); rest time T (days); average slam energy E (Tm·m/m 2 ) Where hammer weight W, drop distance H, and point spacing I, the predetermined reinforcement depth D (m), is obtained by the following formula:
