由于施工难度的影响,以及路堤静荷载、车辆动荷载、地下水的共同作用,高填方路基极易产生过大的整体沉降或不均匀沉降,导致路面出现破损,甚至被破坏,直接影响公路的运行安全、通行能力和使用寿命。因此,为了发现、消减不利因素于萌芽,确保道路在稳定的状态下工作,必须对高填方路基沉降实施有效监测。所谓有效监测,不但包括沉降数据的获取,而且涵盖沉降信息的分析、沉降实际的评价、沉降变化趋势预测预报等。 Due to the difficulty of construction and the joint action of static load of embankment, dynamic load of vehicles and groundwater, the high embankment subsidence can easily cause excessive settlement or uneven settlement, resulting in the damaged or even destroyed road surface, which directly affects the highway Operational safety, accessibility and service life. Therefore, in order to find out that the advent of adverse factors in the bud, to ensure that the road to work in a stable state, the settlement of high embankment must be effectively monitored. The so-called effective monitoring includes not only the acquisition of settlement data but also the analysis of settlement information, the actual evaluation of settlement and the prediction and forecast of settlement trend.
