【摘要】：為了研究數(shù)值模擬方法在排水板堆載預(yù)壓加固軟基的固結(jié)沉降計算中的實用性和有效性。結(jié)合某填海造地道路地基處理工程,探討了塑料排水板堆載預(yù)壓法處理軟基的固結(jié)機理。基于有限元分析軟件ABAQUS,采用擴展的Drucker-Prager本構(gòu)模型,建立塑料排水板堆載預(yù)壓法處理軟基的固結(jié)沉降有限元計算模型,考慮分級加載情況,對加固軟基的固結(jié)沉降過程進(jìn)行數(shù)值模擬計算,并將計算結(jié)果與實測數(shù)據(jù)進(jìn)行了對比分析。研究結(jié)果表明:軟基固結(jié)沉降的數(shù)值模擬曲線與實測曲線變化趨勢基本一致,能夠較好地模擬各級堆載預(yù)壓過程中的軟基沉降速率變化規(guī)律;模擬曲線比實測曲線收斂更快,計算值與實測值吻合較好,可為類似工程提供借鑒。
[Abstract]:In order to study the practicability and effectiveness of numerical simulation method in the consolidation settlement calculation of soft foundation strengthened by preloading of drainage slab. In this paper, the consolidation mechanism of soft foundation treated with plastic drainage plate surcharge preloading method is discussed in combination with a reclamation road foundation treatment project. Based on the finite element analysis software Abaqus and using the extended Drucker-Prager constitutive model, the finite element calculation model of consolidation settlement of soft foundation is established by preloading method of plastic drainage board. The process of consolidation and settlement of reinforced soft foundation is simulated and compared with the measured data. The results show that the numerical simulation curve of the consolidation settlement of soft foundation is basically consistent with the measured curve, which can well simulate the variation law of the settlement rate of soft foundation during the preloading process, and the simulation curve converges faster than the measured curve. The calculated values are in good agreement with the measured values, which can be used for reference in similar projects.
