抛石围堤施工期间位移沉降规律分析

通过对围堤施工情况跟踪及监测数据整理分析,探索抛石围堤施工期间的位移、沉降规律。施工过程中控制加载速率及分层加载高度,每次加载均在达到设计要求的恒载时间及监测数据稳定后进行,并采取减小分层加载厚度、堤身两侧反压同步施工、镇脚石施工及时跟进、尽可能延长恒载稳定时间等措施行之有效。

Analysis of monitoring data of displacement and settlement in the process of embankment construction

This article explores the laws of displacement and settlement during construction of the riprap embankment based on the analysis of the monitoring data of the construction. The loading rate and the layered loading height shoud be under control in the process of the dyke construction. It is feasible to control the loading speed and layered loading height. Measures such as decreasing the loaded height, loading on both sides of the dyke simultaneously, timely following of apron rockfills and extending the time of permanent load should be taken to make sure the effective and safe dyke construction.
