摘要
扁铲侧胀试验(DMT)作为一种原位测试方法,操作简单、实用性强但应用较少。本文以常州建科大厦地块勘察工程为例,明确了DMT在常州地区的适用情况。通过收集扁铲侧胀试验参数进行统计计算,与室内试验求得的静止侧压力K_(0)和压缩模量E_(s)进行对比分析,对在常州地区利用扁铲侧胀指数进行K_(0)和E_(s)的经验公式进行了校正,总结归纳出适合本地区的公式,为常州地区广泛采用扁铲侧胀试验计算K_(0)和E_(s)提供了依据。
As an in-situ test method,Flat Dilatometer Test(DMT)is simple and practical,but it is rarely used.Taking the plot survey project of Changzhou Jianke building as an example,this paper defines the application of DMT in Changzhou.By collecting the parameters of flat dilatometer test for statistical calculation,comparing and analyzing with the static lateral pressure K_(0) and compression modulus Es obtained from indoor test,the empirical formula of K_(0) and Es using flat dilatometer index in Changzhou area is corrected,and the formula suitable for this area is summarized,which provides a basis for the wide use of Flat Dilatometer Test in Changzhou area to calculate K_(0) and Es.
