Calculation method of composite foundation inter-pile soil bearing capacity characteristic value
The invention relates to the technical field of foundation treatment of civil engineering, in particular to a method for calculating a composite foundation inter-pile soil bearing capacity characteristic value, which comprises the following steps of: determining an inter-pile soil void ratio before reinforcement treatment, determining the diameter and center spacing of a reinforced pile, determining an equivalent diameter after reinforcement according to the layout of the reinforced pile, and calculating the composite foundation inter-pile soil bearing capacity characteristic value. Calculating the void ratio of the soil between the piles after reinforcement treatment, and establishing a bearing capacity characteristic value calculation formula to calculate the bearing capacity characteristic value of the soil between the piles after reinforcement treatment; according to the method, a calculation formula related to soil empirical parameters, the void ratio of the reinforced soil body and the bearing capacity characteristic value of the soil between the reinforced piles is established by considering factors such as the diameter of the reinforced piles, the center distance and the equivalent diameter after reinforcement, and inconvenience and errors caused by dependence on a traditional field test method such as a heavy static sounding test are avoided.
