根据桩土共同作用的原则及荷载传递的规律，推导出分层土中静压桩单桩承载力的计算公式，并根据广东地区的静压桩试桩资料，对公式进行了修正．利用此公式，只需知道土的干容重γ、内聚力Ｃｐ、摩擦角Ψ、压缩模量Ｅｓ及土的轴向变形系数Ｋｖ，即可求得桩的承载力和荷载－沉降曲线．与实测荷载－沉降曲线对比，该公式具有良好的适应性 According to the principle of pile-soil interaction and the law of load transfer, the formula for the bearing capacity of a single-pile static pile in layered soil was deduced, and the formula was revised according to the static pile data of the pile in Guangdong. Using this formula, the bearing capacity and load-settlement curve of the pile can be obtained simply by knowing the dry bulk density γ, the cohesive force Cp, the friction angle Ψ, the compressive modulus Es, and the axial deformation coefficient Kv of the soil. Compared with the measured load-settlement curve, this formula has good adaptability
