This paper respectively uses the method of expansion of cavity and fem to analysis the soil compaction effect of anchor jacked pile while sinking , and compares the calculation result of the two methods by combining effect is valuable to the application of engineering 摘要分別用柱形孔擴張法和有限元方法對錨桿靜壓樁沉樁過程中的擠土效應(yīng)進行了分析,并結(jié)合工程實例對兩種方法計算的結(jié)果進行了比較,很好地探討了沉樁擠土規(guī)律,具有一定的工程實用價值。
Directed against the lack of laboratory equipment that can simulate field vibratory compaction , a vibratory compaction apparatus that can simulate the mechanical structure of vibratory roll , and can regulate vibratory parameters , is developed through the analysis of influence factors of field compaction effect for vibratory roll , such as structure parameters and vibration parameters 本課題針對室內(nèi)缺少能夠模擬現(xiàn)場振動壓實狀況的振動壓實設(shè)備的現(xiàn)狀,在深入分析影響振動壓路機現(xiàn)場壓實效果的因素如振動參數(shù)、結(jié)構(gòu)參數(shù)等的基礎(chǔ)上,自行研制加工了在結(jié)構(gòu)上可以模擬振動壓路機的機械結(jié)構(gòu)且振動參數(shù)都可調(diào)的振動壓實成型設(shè)備。
