摘要

分析了确定复合地基承载力的现况。根据收集到的复合地基承载力检测资料，用双曲线模型、指数模型、灰色模型对复合地基极限承载力进行了预测，并对模型的预测效果进行了分析对比，提出了适合天津市区复合地基的极限承载力预测模型。对预测值进行了修正。根据预测值建立了极限承载力和承载力特征值的关系。

Abstract

Current situation of determining bearing capacity of composite ground is analyzed. Referring collected data of cement mixing pile static load experiments

ultimate bearing capacity of composite ground is predicted by using hyperbolic model

exponential model and grey model. Predicting models that determine ultimate bearing capacity are contrasted and analyzed; and suitable model is proposed. Predicted value is improved. According to predicted value

the relationship between ultimate bearing capacity and characteristic value of bearing capacity is determined.
