Vertical bearing capacity checking calculation method for low-pile bearing platform foundation
The invention discloses a vertical bearing capacity checking calculation method for a low-pile bearing platform foundation. The vertical bearing capacity checking calculation method comprises the following steps that a simplified condition is introduced; a failure condition is determined according to the simplified condition and the space stress characteristics of a pile group bearing platform structure system; functional functions of all components in the pile group bearing platform structure system are determined according to the failure condition; the limit state of the pile group bearing platform structure system is determined according to the functional functions of all the components in the pile group bearing platform structure system; and the effective probability and the failure probability of the pile group bearing platform structure system are determined according to the limit state of the pile group bearing platform structure system. The vertical bearing capacity checking calculation method has the beneficial effects that the reliability of the pile group bearing platform structure system is analyzed, so that the reliability of the whole pile foundation is improved, andthe reasonability of a design scheme is improved.
