BEARING CAPACITY CALCULATION METHOD OF SOIL CEMENT COMPOSITE PILE

摘要

PROBLEM TO BE SOLVED: To provide a new formula capable of accurately calculating bearing capacity of a soil cement composite pile by simple calculation.;SOLUTION: When bearing capacity of the soil cement composite pile obtained by twistedly penetrating the existing pile having spiral wings into a soil cement columnar body is calculated, the calculation of friction stress τacting on the circumferential surface of the composite pile is made with one formula τ=α+βN (α, β represents a fixed number obtained by correlation of a diameter of the existing pile body, a diameter of the spiral wing and a diameter of the soil cement columnar body) for using N value through a standard penetration test without depending on sorts of the ground.;COPYRIGHT: (C)2003,JPO
