一种用于堤坝动态监测的电法观测系统及方法An electrical observation system and method for dynamic monitoring of embankments

技术领域technical field

本发明涉及一种用于堤坝安全动态监测的电法观测系统及方法，通过长期定时动态监测堤坝等水工建筑物的电场变化情况，寻找其因内部结构变化而导致的安全隐患。The invention relates to an electrical method observation system and method for dynamic monitoring of dam safety, through long-term and regular dynamic monitoring of electric field changes of hydraulic structures such as dams, to find potential safety hazards caused by internal structure changes.

背景技术Background technique

目前对于堤坝等水工建筑物的安全监测主要通过监测堤坝等水工建筑物的形变、渗流、压力、温度等的变化来实现。At present, the safety monitoring of hydraulic structures such as dams is mainly realized by monitoring the changes of deformation, seepage, pressure, temperature, etc. of hydraulic structures such as dams.

采用以上方法对堤坝安全进行监测主要通过布设在堤坝周边或堤坝内部的传感器来获取堤坝的变化，从而实现堤坝的安全监测。若采用在堤坝周边布置测量堤坝变化的传感器，则需要当堤坝表面发生变化时，才能监测到堤坝的安全隐患，而一旦堤坝表面发生变化，堤坝内部可能已经发生非常明显的变化，堤坝的危险性已经很高，可能导致留给治理安全隐患的时间很短，因此该方法的预见性不强。若采用在堤坝建设时预埋测量堤坝变化的传感器，则由于传感器的加入，有可能改变堤坝的应力结构，且一旦传感器出现故障，则无法进行监测。如果对于已建设好的堤坝，要在堤坝内部安装传感器，则需要对堤坝进行钻孔等破坏性作业，造成堤坝的结构破坏。故目前常用的堤坝安全监测手段和方法均存在一些问题。Using the above method to monitor the safety of the dam mainly obtains the changes of the dam through the sensors arranged around the dam or inside the dam, so as to realize the safety monitoring of the dam. If sensors are arranged around the dam to measure the change of the dam, it is necessary to monitor the safety hazard of the dam when the surface of the dam changes, and once the surface of the dam changes, very obvious changes may have occurred inside the dam, and the danger of the dam Already high, it may lead to a short time left for governance security risks, so the predictability of this method is not strong. If the sensors used to measure the changes of the embankment are pre-embedded during the construction of the embankment, the stress structure of the embankment may be changed due to the addition of the sensor, and once the sensor fails, monitoring cannot be carried out. If sensors are to be installed inside the dam, it is necessary to perform destructive operations such as drilling on the dam, causing structural damage to the dam. Therefore, there are some problems in the commonly used means and methods of dam safety monitoring.
