技术领域Technical Field
本发明涉及边坡监测技术领域，具体为一种埋入式多角度边坡稳定性动态监测系统。The invention relates to the technical field of slope monitoring, and in particular to an embedded multi-angle slope stability dynamic monitoring system.
背景技术Background technique
边坡主要包括自然边坡和人工边坡两种类型。自然边坡主要是指在自然作用下形成的陡崖、斜坡、海岸、河岸等；人工边坡主要是指人类工程活动形成的具有坡度的坡面，如露天边坡、水库库区边坡、基坑边坡等。近年来，随着露天采矿逐渐转向深部开采，形成了许多高陡边坡，这些边坡的稳定性状态不仅涉及到矿山开采的安全，同时也涉及到周边整体环境的安全。因此对边坡的正确认识、合理设计、及时监测、准确预报预测、恰当处治，避免和减小边坡变形失稳破坏所造成的灾害和损失，是当前露天开采深部开采发展急需解决的问题。边坡安全监测及预测预报是边坡稳定性研究中的核心内容，由于影响边坡稳定性的因素众多且复杂，边坡岩土体的力学参数不仅难以确定，而且也不是一成不变的，因此难以确定边坡所处的稳定性状态，必须研发一种既能够实时监测边坡稳定性，又能反映边坡危险区域的监测装置。Slopes mainly include natural slopes and artificial slopes. Natural slopes mainly refer to steep cliffs, slopes, coasts, river banks, etc. formed by natural action; artificial slopes mainly refer to slopes with slopes formed by human engineering activities, such as open-pit slopes, reservoir slopes, foundation pit slopes, etc. In recent years, with the gradual shift from open-pit mining to deep mining, many high and steep slopes have been formed. The stability of these slopes not only involves the safety of mining, but also the safety of the surrounding overall environment. Therefore, the correct understanding, reasonable design, timely monitoring, accurate prediction and forecasting, and appropriate treatment of slopes to avoid and reduce the disasters and losses caused by slope deformation, instability and destruction are the problems that need to be solved urgently in the current development of open-pit mining and deep mining. Slope safety monitoring and prediction are the core content of slope stability research. Due to the numerous and complex factors affecting slope stability, the mechanical parameters of the slope rock and soil are not only difficult to determine, but also not static. Therefore, it is difficult to determine the stability state of the slope. It is necessary to develop a monitoring device that can monitor the stability of the slope in real time and reflect the dangerous area of the slope.
根据中国专利申请号2021103763353公开的一种埋入式多角度边坡稳定性动态监测装置，可以实现对边坡内部变形进行实时、多角度监测，并且能够利用软件对数据进行及时处理，实现了边坡稳定性监测的实时化与简单化，同时多台设备可以连接使用，根据监测数据能够反应边坡体内部潜在危险区域；但是该边坡稳定性动态监测装置无法对边坡的数据进行准确的测量，无法实现精准的警报，使得边坡施工现场的安全性降低。According to an embedded multi-angle slope stability dynamic monitoring device disclosed in Chinese patent application No. 2021103763353, real-time, multi-angle monitoring of the internal deformation of the slope can be achieved, and the data can be processed in a timely manner using software, thereby realizing real-time and simplified slope stability monitoring. At the same time, multiple devices can be connected and used, and the potential dangerous areas inside the slope body can be reflected based on the monitoring data; however, the slope stability dynamic monitoring device cannot accurately measure the slope data, and cannot achieve accurate alarms, which reduces the safety of the slope construction site.

进一步地，所述埋入式监测机构包括上锚桩和下锚桩，所述上锚桩埋设在边坡的上部，所述下锚桩埋设在边坡的下部，所述上锚桩和下锚桩之间设有位移检测装置。Furthermore, the embedded monitoring mechanism includes an upper anchor pile and a lower anchor pile, the upper anchor pile is buried in the upper part of the slope, the lower anchor pile is buried in the lower part of the slope, and a displacement detection device is provided between the upper anchor pile and the lower anchor pile.
进一步地，所述位移检测装置包括电子弹力测量器和连接在所述电子弹力测量器两端的弹性绳，两个所述弹性绳远离电子弹力测量器的端部分别固定连接在上锚桩和下锚桩上，所述电子弹力测量器和数据处理装置电性连接。Furthermore, the displacement detection device includes an electronic elastic force meter and elastic ropes connected to both ends of the electronic elastic force meter, the ends of the two elastic ropes away from the electronic elastic force meter are respectively fixedly connected to the upper anchor pile and the lower anchor pile, and the electronic elastic force meter is electrically connected to the data processing device.
进一步地，所述位移检测装置监测滑坡位移时：Furthermore, when the displacement detection device monitors the landslide displacement:
将上锚桩和下锚桩分别固定在边坡的上部和下部，将电子弹力测量器通过两个弹性绳分别连接在上锚桩和下锚桩上，让弹性绳处于拉伸的状态，电子弹力测量器测量出弹性绳之间弹力F，根据胡克定律，F＝kX，k为弹性绳的弹性系数，X为弹性绳的形变距离；测量原始状态下，边坡上的上锚桩和下锚桩构成一个虚拟的直角三角形，上锚桩和下锚桩之间的直线距离S，上锚桩和下锚桩之间水平距离为L，上锚桩和下锚桩之间垂直高度为H；The upper anchor pile and the lower anchor pile are fixed on the upper and lower parts of the slope respectively, and the electronic elastic force measuring device is connected to the upper anchor pile and the lower anchor pile through two elastic ropes respectively, so that the elastic ropes are in a stretched state, and the electronic elastic force measuring device measures the elastic force F between the elastic ropes. According to Hooke's law, F=kX, k is the elastic coefficient of the elastic rope, and X is the deformation distance of the elastic rope; in the original state of measurement, the upper anchor pile and the lower anchor pile on the slope form a virtual right triangle, the straight-line distance between the upper anchor pile and the lower anchor pile is S, the horizontal distance between the upper anchor pile and the lower anchor pile is L, and the vertical height between the upper anchor pile and the lower anchor pile is H;
(1)当边坡发生滑坡后，上锚桩和下锚桩的直线距离为S1，边坡滑坡的距离为S2；(1) When the slope slides, the straight-line distance between the upper anchor pile and the lower anchor pile is S1, and the distance of the slope slide is S2 ;
此时电子弹力测量器测得的弹力为F1＝kX1，X1＝F1/k,At this time, the elastic force measured by the electronic elastic force measuring device is F 1 = kX 1 , X 1 = F 1 /k,
S2＝2×(X-X1)，S 2 =2×(XX 1 ),
S2＝2×(F/k-F1/k)；S 2 =2×(F/kF 1 /k);
当电子弹力测量器测得弹力为0时，则边坡已经发生严重的滑坡现象；When the electronic elastic force measuring device measures the elastic force to be 0, the slope has already experienced serious landslide;
(2)当边坡发生沉降后，上锚桩和下锚桩的直线距离为S3，上锚桩和下锚桩之间水平距离L不变，上锚桩和下锚桩之间垂直高度为H1，沉降距离为H2，此时电子弹力测量器测得的弹力为F1＝kX1，X1＝F1/k,(2) When the slope settles, the straight-line distance between the upper and lower anchor piles is S3, the horizontal distance L between the upper and lower anchor piles remains unchanged, the vertical height between the upper and lower anchor piles is H1, and the settlement distance is H2. At this time, the elastic force measured by the electronic elastic force measuring device is F 1 = kX 1 , X 1 = F 1 /k,
S3＝2×((S/2-F/k)+F1/k)；S 3 =2×((S/2-F/k)+F 1 /k);
根据勾股定理可知：According to the Pythagorean theorem:
S3 2＝L2+H1 2；S 3 2 =L 2 +H 1 2 ;
H2＝H-H1； H2 = HH1 ;
当电子弹力测量器测得弹力为0时，则边坡已经发生严重的沉降现象；When the electronic elastic force measuring device measures the elastic force to be 0, the slope has already experienced serious settlement;
因此，根据电子弹力测量器测量出的弹力变化，便可以判断边坡的滑坡距离或沉降距离，从而达到准确监控的效果。Therefore, according to the change of elastic force measured by the electronic elastic force measuring device, the landslide distance or settlement distance of the slope can be determined, thereby achieving the effect of accurate monitoring.
进一步地，所述上锚桩和下锚桩均由锚桩头、锚桩杆和监测器安装部组成，所述锚桩头设置在锚桩杆的上端，所述监测器安装部固定设置在锚桩杆的中部，所述监测器安装部的外周分别设有渗透计、土压力计和地下水位计，所述渗透计用于测量下雨后边坡内渗流的压力；所述土压力计用于测量监测器安装部周围的内部应力；所述地下水位计用于测量边坡内部水位情况。Furthermore, the upper anchor pile and the lower anchor pile are composed of an anchor head, an anchor rod and a monitor mounting part. The anchor head is arranged at the upper end of the anchor rod, and the monitor mounting part is fixedly arranged in the middle part of the anchor rod.

位移检测装置监测滑坡位移时：When the displacement detection device monitors the landslide displacement:
将上锚桩31和下锚桩34分别固定在边坡的上部和下部，将电子弹力测量器33通过两个弹性绳32分别连接在上锚桩31和下锚桩34上，让弹性绳32处于拉伸的状态，电子弹力测量器33测量出弹性绳32之间弹力F，根据胡克定律，F＝kX，k为弹性绳32的弹性系数，X为弹性绳32的形变距离；测量原始状态下，边坡上的上锚桩31和下锚桩34构成一个虚拟的直角三角形，上锚桩31和下锚桩34之间的直线距离S，上锚桩31和下锚桩34之间水平距离为L，上锚桩31和下锚桩34之间垂直高度为H；The upper anchor pile 31 and the lower anchor pile 34 are fixed to the upper and lower parts of the slope respectively, and the electronic elastic force measuring device 33 is connected to the upper anchor pile 31 and the lower anchor pile 34 respectively through two elastic ropes 32, so that the elastic ropes 32 are in a stretched state, and the electronic elastic force measuring device 33 measures the elastic force F between the elastic ropes 32. According to Hooke's law, F=kX, k is the elastic coefficient of the elastic rope 32, and X is the deformation distance of the elastic rope 32; in the original state of measurement, the upper anchor pile 31 and the lower anchor pile 34 on the slope form a virtual right triangle, the straight-line distance between the upper anchor pile 31 and the lower anchor pile 34 is S, the horizontal distance between the upper anchor pile 31 and the lower anchor pile 34 is L, and the vertical height between the upper anchor pile 31 and the lower anchor pile 34 is H;
(1)当边坡发生滑坡后，上锚桩31和下锚桩34的直线距离为S1，边坡滑坡的距离为S2；(1) When the slope slides, the straight-line distance between the upper anchor pile 31 and the lower anchor pile 34 is S1, and the distance of the slope slide is S2 ;
此时电子弹力测量器33测得的弹力为F1＝kX1，X1＝F1/k,At this time, the elastic force measured by the electronic elastic force measuring device 33 is F 1 = kX 1 , X 1 = F 1 /k,
S2＝2×(X-X1)，S 2 =2×(XX 1 ),
S2＝2×(F/k-F1/k)；S 2 =2×(F/kF 1 /k);
当电子弹力测量器33测得弹力为0时，则边坡已经发生严重的滑坡现象；When the elastic force measured by the electronic elastic force measuring device 33 is 0, the slope has already experienced a serious landslide;
(2)当边坡发生沉降后，上锚桩31和下锚桩34的直线距离为S3，上锚桩31和下锚桩34之间水平距离L不变，上锚桩31和下锚桩34之间垂直高度为H1，沉降距离为H2，此时电子弹力测量器33测得的弹力为F1＝kX1，X1＝F1/k,(2) When the slope settles, the straight-line distance between the upper anchor pile 31 and the lower anchor pile 34 is S3, the horizontal distance L between the upper anchor pile 31 and the lower anchor pile 34 remains unchanged, the vertical height between the upper anchor pile 31 and the lower anchor pile 34 is H1, and the settlement distance is H2. At this time, the elastic force measured by the electronic elastic force measuring device 33 is F 1 = kX 1 , X 1 = F 1 /k,
S3＝2×((S/2-F/k)+F1/k)；S 3 =2×((S/2-F/k)+F 1 /k);
根据勾股定理可知：According to the Pythagorean theorem:
S3 2＝L2+H1 2；S 3 2 =L 2 +H 1 2 ;
H2＝H-H1； H2 = HH1 ;
当电子弹力测量器33测得弹力为0时，则边坡已经发生严重的沉降现象；When the elastic force measured by the electronic elastic force measuring device 33 is 0, the slope has already undergone serious settlement;
因此，根据电子弹力测量器33测量出的弹力变化，便可以判断边坡的滑坡距离或沉降距离，从而达到准确监控的效果。Therefore, according to the change of the elastic force measured by the electronic elastic force measuring device 33, the landslide distance or settlement distance of the slope can be determined, thereby achieving an accurate monitoring effect.
该埋入式多角度边坡稳定性动态监测系统，通过电子弹力测量器33和连接在电子弹力测量器33两端的弹性绳32配合使用，通过监测电子弹力测量器33上的弹力变化，由数据处理装置1进行计算边坡的滑坡距离和沉降距离，准确性更高，操作也较为方便，且能够监测各级边坡的位移和整体位移关系。The embedded multi-angle dynamic monitoring system for slope stability is used in conjunction with an electronic elastic force measuring device 33 and an elastic rope 32 connected to both ends of the electronic elastic force measuring device 33. By monitoring the elastic force changes on the electronic elastic force measuring device 33, the data processing device 1 calculates the landslide distance and settlement distance of the slope. The system has higher accuracy and is more convenient to operate. It can also monitor the displacement of each level of the slope and the overall displacement relationship.
