摘要
依据室内压缩试验研究成果,获取不同固结压力下的固结系数,结合分级加载固结度理论,依照现场施工加载的情况逐级改变计算参数,预测软土地基的沉降过程。结果表明:将计算结果与实测结果进行对比,逐级改变计算参数法得到的沉降量过程与实测值吻合程度高,验证了提出的计算方法的合理性,可应用于软土地基固结沉降量预测。
From indoor compression tests,the consolidation coefficients under different consolidation pressures were obtained,combined with the theory of graded loading consolidation degree,the calculation parameters were changed step by step according to the conditions of on-site construction loading,and the settlement process of soft soil foundation was predicted.The results show that the calculation results are compared with the measured results,and the settlement process obtained by gradually changing the calculation parameters method is in good agreement with the measured values,which verifies the rationality of the proposed calculation method and can be applied to the consolidation settlement of soft soil foundations prediction.
