摘　　要：相较于不改变地基土的工程力学性质、而采取改变基础形式的天然地基上的相对独立的浅基础设计,复合地基与基础设计,就是针对在地基土中设置增强体,以改善地基土的工程力学性质为目的的地基加固处理后的浅基础设计。本文通过对结构工程师做上部结构和基础设计、岩土工程师做复合地基设计的不足进行剖析,基于现有设计规程、规范理论,就选取复合地基与基础设计计算参数进行探讨分析,提出复合地基与基础一体化设计理念。随着计算机应用的普及,可将复杂的数学方程公式和工程地质条件,通过电子计算技术和模拟进行求解,达到优化设计的目的。本文有关复合地基与基础一体化设计中的若干问题的探讨分析和结论,可为工程技术人员进行复合地基与基础设计提供参考。Compared with the relatively independent shallow foundation design on the natural foundation that changes the basic form without changing the engineering mechanical properties of the foundation soil,the composite foundation and base design are the design of shallow foundation after founadation reinforcement treatment,which set the reinforcement in the foundation soil to improve the engineering mechanical properties.This paper analyzes the insufficiency that structural engineers design superstructure and foundation and geotechnical engineers design composite foundation.Based on the existing design codes,this paper discusses on the selection of calculation parameters about composite foundation and base design,and proposes the integrated design concept of composite foundation and base.With the popularization of computer applications,complex mathematical equations and engineering geological conditions can be solved by electronic computing technology and numerical simulation.This paper discusses and analyzes on some problems in the integrated design of composite foundation and base,which can provide reference for engineering and technical personnel to carry out composite foundation and base design.
