软土地基变形的混沌性与承载力识别

IDENTIFICATION OF SOFT FOUNDATION CAPACITY ON CHAOTIC MODEL

摘要: 本文以混沌理论为基础, 分析了软土地基变形的混沌性态, 并采用映射函数f(x)=ax2+c来拟合软土地基的沉降-载荷曲线。根据映射函数的不动点, 对软土地基加固前后的承载力进行了识别, 并与按相对变形值确定的承载力进行了比较。

Abstract: Chaotic characteristication of soft soil foundation is analyzed on the basis of chaotic theory and its capacity can be also identifited. Comparing with the value of P 0.02 , the capacity by means of chaotic model is safe in the engineering.
