摘要
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。
The formula of bearing capacity for single pile in stratified soil is induced according to the principle of the co action of the pile and ground, and the rule of load transfer. Adjustment is made on the basis of the data collected in pile driving in Guangdong Province. With the help of this formula, pile′s bearing capacity and load sinking curve can be obtained if the following parameters of the soil are known: dry unit weight, cohesion, compression modulus and coefficient of axis deportation. Compared with the measured load sinking curve, the formula demonstrated very good compatibility.
