Method for calculating consolidation degree of high-replacement-rate discrete material pile composite foundation
The invention belongs to methods for calculating the consolidation degree of composite foundations, and particularly relates to a method for calculating the consolidation degree of a high-replacement-rate discrete material pile composite foundation. The method includes the steps that step1, according to plane arrangement mode of a pile body, the replacement rate of the pile body is determined, and whether the method needs to be adopted for calculation or not is judged; step2, loading parameters are determined; step3, construction disturbance effect parameters of the pile body are determined; step4, the permeability coefficients of the pile body and soil body and the pile-soil compression modulus ratio are determined; step5, non-dimensionalization is performed on calculation parameters; step6, Fc is calculated; step7, the consolidation degree of the composite foundation is calculated. The method is suitable for calculating the consolidation degree when the high-replacement-rate (large diameter) pile is adopted for accelerating consolidating of the soft soil foundation in the fields of road engineering, industrial and civil construction engineering, port and waterway engineering and others. The method has the advantages that the method can be used for calculating the consolidation degree when the discrete material pile is adopted for accelerating consolidating of the soft soil foundation in the fields of road engineering, industrial and civil construction engineering, port and waterway engineering and others, the method is particularly suitable for working conditions where the replacement rate of discrete material piles is above 15%, and expected results can be obtained through iterative calculation.
