Description

Landslide geological disasters are common geological disasters in engineering construction, and human engineering activities such as large-scale hydraulic engineering construction, mountain road subgrade engineering, petroleum pipeline laying and the like can directly or indirectly induce landslide and start landslide, so that serious human and financial losses are caused. Therefore, the landslide deformation evolution law is known by monitoring the landslide, and the evolution stage is judged, so that the landslide monitoring method has important significance for landslide early warning and prevention, and engineering construction and people safety guarantee.

The real-time observation and measurement of displacement field, stress field, temperature field, seepage field, chemical field and other environmental factors (rainfall, reservoir water level and the like) influencing the landslide development by applying the comprehensive technical means is important field information monitoring. However, due to the limitation of monitoring technology, for monitoring a landslide 'field', the displacement field is mainly emphasized at present, and other 'fields' are often used as auxiliary parameters of the displacement field, and are not fully emphasized. Meanwhile, because the underground monitoring environment is not original in drilling disturbance, the field in the existing monitoring is only approximate, and how to extend out to a certain distance based on the drilling to realize the monitoring in the undisturbed underground environment becomes an important requirement for landslide multi-field information monitoring. Meanwhile, the existing landslide depth monitoring technology has the defects of dispersed sensor types and types, low utilization rate of monitored data information, low precision and poor correlation degree, is often applied independently in landslide deformation evolution law research, solves the problems of low efficiency, high cost and poor correlation in multi-field monitoring information and is another important requirement for landslide multi-field information monitoring. The 'one-hole multi-measurement' means that multiple or multifunctional monitoring instrument equipment is arranged in a single drilling hole, so that the purposes of single-line control and integrated acquisition of multiple information parameters are achieved, and the problems can be effectively solved. But placing multiple integrated sensors to the sidewall in a small borehole has certain difficulties.

Therefore, aiming at the problems, the design of a set of device for monitoring multiple geological information with mature technology, high efficiency and reliability and one hole for multiple measurements at the deep part of the landslide is of great significance.
