路基的横、纵断面不均匀沉降变形是路基监测的一项重要内容,针对测试仪在路基横断面竖向沉降测试中的应用,简要介绍了伺服加速度式测斜仪的原理,工程实例测试表明：影响剖面沉降测试仪测试精度的因素主要包括环境因素、仪器本身和人为的因素;剖面沉降测试的关键因素是正反向测试的测点位置相同;随着测试距离的增大,所产生的初始高程误差增加,对沉降测值影响越大。

The measurement of the uneven-settlement-caused deformation between the transverse and the longitudinal sections of the roadbed is an important part of the content of the monitoring of the subgrade.With the application of the inclinometer to the measurement of the vertical settlement in the cross section of the subgrade taken into account,the principle of the servo acceleration-type inclinometer is briefly introduced in the paper.The results of the measurement of some practical projects show:①the factors that affect the accuracy of the sectional-settlement inclinometer include environmental factors,the instrument itself,and the human factor;②the key factor of the tests performed with the sectional-settlement inclinometer lies in the fact that the position of the measuring points should be the same in both the positive and negative tests;③with the distance to be measured becoming longer and the error in the initial elevation gradually increasing,the effects on the accuracy of the values of the measured settlement will be greater.
