[0057] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0058] A calculation method for a piled raft foundation disclosed by the present invention is described from three aspects as follows.
[0059] 1) Basic principles
[0060] Pile-raft foundations are widely used in hydraulic foundation engineering. According to a large number of test results and monitoring data, the stress and deformation characteristics of pile-raft foundations are that when the pile-raft bears a load not greater than the design load, its static load test The p ~ s curve is basically linear.
[0061] The greater the displacement of a certain point in the foundation, the greater the compression of the point, and the greater the elastic resistance strength of the corresponding soil or pile to the foundation. This relationship is ...
