摘要
结合西南某高填方机场监测数据资料,分析研究高填方机场原地基沉降的简易计算方法。根据原地基的条件将地基分为正常固结、欠固结和超固结三种情况,并分析三种情况的地基沉降量计算理论方法。利用监测数据资料对分层总和法计算原地基沉降的压缩模量Es和经验系数ψs进行反算,通过反算系数对原地基沉降进行计算。
This paper presents a case history of monitoring the performance of high fill embankments in an airport construction in southwest China.A simplified settlement estimation of the soils underneath the high fill embankment is also proposed.Based on the normally consolidated,under-consolidated and over-consolidated status of original soils,the compression modulus and the settlement of soils under three states are determined.The compression modulus Es and the empirical coefficient ψs are also back analyzed by using the monitored data.
