Description
Technical Field
The utility model relates to a landslide mass monitoring field, concretely relates to road both sides side slope real-time supervision early warning system based on stress method.
Background
The side slopes on two sides of the expressway/railway are affected by various extreme weathers such as heavy rainstorm and the like, the water content of the side slopes is increased due to overlarge rainfall, the underground water level is increased, the shearing resistance of the soil body is rapidly reduced, and in addition, the rock mass structure is damaged to a certain extent due to the scouring effect of rainwater on the rock mass. The internal shear resistance of the side slope soil body can be reduced to a certain extent, a slip surface is formed in the soil body, and soil body landslide is caused, so that serious negative effects can be caused on the driving or train safety of the highway. Because the speed of the highway automobile and the railway is fast, if the early warning is not timely carried out, traffic accidents such as train derailment, train turnover and the like can be caused. For slope protection early warning on expressways and railways, economic benefit and real-time high efficiency are two aspects which must be considered. The sensors applied to the slope deformation monitoring and early warning system at present mainly comprise an anchor cable meter, a soil pressure meter and the like.
The anchor cable dynamometer is mainly used for monitoring the anchoring state of prestress of hydraulic structures and other concrete structures, rock slopes, bridges and the like for a long time, and has the defects of complicated installation process and higher requirement. And data need artifical reading, and the security is low, and data can not be transmitted in real time.
The soil pressure gauge has the advantages of simple installation and low cost; the defect is that the soil pressure gauge can move along with the landslide body, the internal pressure of the landslide body at a fixed point position cannot be measured, and data measured by the soil pressure machine cannot be transmitted in real time.
For the side slope protection measures at two sides of the expressway or the railway, the main method is to arrange an active or passive protective net and the like at the side slope of the road.
The active protection system covers and wraps various flexible nets mainly comprising steel wire rope nets on a slope or rocks to be protected so as to limit weathering spalling or damage of slope rock soil bodies and rock collapse (reinforcement function), or control falling rocks to move within a certain range (containment function). The system has certain openness and can protect landslide to a certain extent. However, the method cannot effectively warn landslide occurrence, does not know the internal information of soil on the road side slope, and causes great damage to roads and vehicles when the protective net is difficult to intercept once major landslide occurs.
The passive protective net is composed of four main parts, namely a steel wire rope net, an annular net, a layer of iron wire grating added when small rockfall needs to be intercepted, a fixing system (an anchor rod, a pull anchor rope, a base and a supporting rope), a pressure reducing ring and a steel column. The steel columns and the steel wire rope net are connected and combined to form a whole, and surface protection is formed on a protected area, so that falling of a collapsed rock soil body is prevented, and a side slope protection effect is achieved. The passive protection net can only prevent falling rocks and small soil bodies on the side slope from sliding off, and when a landslide occurs, the passive protection net cannot intercept the falling soil bodies, so that the road and vehicles passing the road can be damaged.
