Description

A kind of multi-parameter monitoring system and monitoring method outside the deep hole of sliding body

technical field

The invention relates to the field of geological disaster monitoring and prevention, in particular to a multi-parameter monitoring system and a monitoring method outside a deep hole of a sliding body.

Background technique

Landslide geological disasters are large-scale and sudden, often accompanied by catastrophic results such as road burial and house damage, and are the most common type of geological disasters. Landslide geological hazard presents a certain evolution law and supporting system in time and space. Its formation and development reflect the dynamic evolution process of the geological body and have the characteristics of multi-field coupling. The combined action of multiple fields is the endogenous driving force of landslide evolution, which determines the complexity and diversity of landslide geological disasters, and determines the basic properties and boundary conditions of landslides. Therefore, through the monitoring of multi-field information such as seepage field, displacement field, stress, temperature field and electromagnetic field, the establishment of multi-field information characteristic parameter monitoring methods and technologies is an effective way to reveal the evolution mechanism, and realize the prediction and prevention of landslides.

There are obvious deficiencies in the study of landslide evolution based on traditional landslide monitoring technology. Due to the complex prediction and early warning indicators and the difficulties in the theoretical method of data fusion, the monitoring projects are often dominated by displacement, resulting in the single content of monitoring equipment and weak functions, which have important effects on the landslide evolution process (seepage field, stress field, temperature field) etc.) monitoring content is not complete and the degree of correlation is not enough, so it cannot meet the needs of multi-field evolution characteristics analysis of landslides, and it is difficult to support the establishment of a landslide catastrophic criterion system under the action of multiple fields. The existing multi-information parameter integrated monitoring technologies include two types. One is to independently deploy instruments suitable for monitoring a specific physical quantity according to the needs of different monitoring contents, so as to realize the comprehensive integration of multi-information parameters in the landslide area; The first type is to arrange a set amount of drilling holes in the landslide body, and each drilling hole is integrated with instruments or sensors for monitoring various information parameters, so as to realize "multiple measurements in one hole". The former multi-instrument independent distributed integrated monitoring method has been widely used. This method requires a large investment in capital, manpower, and material resources, and the sensor types are scattered. The monitoring data and information have low utilization rate, low precision, and poor correlation. The latter monitoring environment is mainly in the hole, which is suitable for deep inclination measurement and groundwater level measurement, but it is difficult to accurately measure parameters such as pore water pressure and water content under in-situ conditions. At the same time, this method has poor environmental adaptability. After the enlargement, the instruments in the hole are mostly damaged and fail.

Obviously, there is no technology to realize multi-information joint monitoring outside the deep borehole of the landslide. Therefore, it is particularly important to develop a multi-parameter joint monitoring system for the deep borehole outside the landslide to realize "multiple measurements in one hole" under in-situ conditions. urgent.
