The invention discloses a method for computing composite foundation bearing capacity characteristic values by the aid of pile and soil load test results. The method includes steps of carrying out pileand soil load tests; determining basic data by the aid of design drawing and P-s curves obtained at the step 1; computing composite foundation bearing capacity limit values by the aid of the basic data obtained at the step 2; determining the composite foundation bearing capacity characteristic values f<k>. Each composite foundation bearing capacity characteristic value f<k> is a half of the corresponding composite foundation bearing capacity limit value computed at the step 3. Compared with the prior art, the method for computing the composite foundation bearing capacity characteristic valuesby the aid of the pile and soil load test results has the advantages that results are few in error, the method is high in computational accuracy, and the like.
Description
technical field [0001] The invention relates to a calculation method in the field of construction, in particular to a method for calculating the characteristic value of the bearing capacity of a composite foundation by using pile and soil load test results. Background technique [0002] Composite foundation is a widely used foundation form. Vertically reinforced composite foundation refers to the composite foundation in which vertical reinforcements (hereinafter referred to as piles) such as rigid piles, flexible piles, and bulk material piles are added to the foundation soil (rock layer and soil layer, hereinafter referred to as foundation soil), hereinafter referred to as composite foundation foundation. According to relevant technical standards, when designing, the bearing capacity of composite foundation is calculated according to Formula 1: [0003] f k = mf ak +β(1-m)f sk (1) [0004] where f k is the eigenvalue of the bearing capacity of the composite foundati...
