对土压缩性指标取值标准的探讨

A Study on Choosing Value Standards of Soil Compressibility Index

在《建筑地基基础设计规范》(GBJ7-89)中 ,计算土的压缩性指标时压力段取值标准与旧规范不同。本文主要是用这两种不同取值标准计算地基土的沉降量并进行比较 ,得出相对偏差的变化特点。

The choosing value standards of calculating soil compressibility in a pressure period in lately issued <DESIGN STANDARDS OF CONSTRACTION FOUNDATION>(GBJ7-89)are different from that in former issued.This paper tries to find out the changing regularity of relative deviation by calculating the settlement quantity of foundation soil according to two different choosing value standards and comparing them with each other.
