用离心模型试验研究高填方地基沉降
Centrifugal Model Tests for Settlement of High Embankment
-
摘要: 以西南地区某机场为工程背景,利用离心模型试验系统研究了高填方地基的变形特性.结果表明,对于 试验所用土体,高填方地基的沉降特征为“沉降大,压实快”,沉降主要发生在施工期间,施工后沉降小于总沉降 的10%.Abstract: By taking an airport in the southwest of China as an example, a group of centrifugal model tests are carried out to investigate the deformation characteristics of high embankment. The research results show that great settlement and fast compression are the main characteristics of high embankment for the soil used in the tests, above 90% of settlement occurs during the construction, and below 10% after the construction.
