摘　　要：为了监测防波堤表层的位置变化来控制加载速率和防波堤堤脚软弱地在堤身填筑过程中的水平位移,及时反映堤身稳定性情况以及监测,分析地基的位移速率,发现失稳迹象并及时报警,对防波堤地基表层和深层进行了水平位移的监测。监测结果表明:表层,外侧水平位移量明显大于内侧水平位移量;深层水平位移未出现超过报警值的情况,截至后期,地基深层位移每月变化量较小,不会对堤体的稳定造成影响。In order to monitor the position change of breakwater’s surface layer,control the load rate and the horizontal displacement of breakwater in the construction,and timely monitor the stability of breakwater,the horizontal displacement monitoring is made for the surface and deep layer of breakwater foundation.The results show that the external horizontal displacement is significantly more than the inner horizontal displacement of the surface layer,and the horizontal displacement of the deep layer hasn’t exceeded the alarm value.At the latter stage,monthly less displacement of the deep layer will not affect the stability of breakwater,which also shows that the monitoring of horizontal displacement protects and guarantees the project to a certain extent.
