Description

DEVICES AND A NEW METHOD FOR MONITORING
MULTIPLE GEOLOGICAL PARAMETERS OUTSIDE
BOREHOLE IN SLIDING MASS
BACKGROUND OF THE INVENTION
I. Field of the Invention [0001] The invention relates to the field of landslides disasters monitoring, and particularly to devices and a new method to monitoring multiple geological parameters outside borehole in sliding mass.

2. Description of Related Art [0002] Landslides cause disastrous results, such as burying roads and destroying houses. To manage landslide risks, a better way to install monitor sensors inside the sliding mass is needed. Ideally it would be possible to monitor groundwater pressures, internal landslide deformations, ground temperatures, and other physical parameters at selected locations inside the landslide to understand the landslide behavior and to aid in predicting sudden landslide movements.

[0003] The conventional way to monitor a landslide is to drill boreholes, case the holes with PVC pipe and then to monitor parameters such as deformation and fluid pressures from within the cased borehole. This method limits the type of measurement that can be made at their locations.

[0004] The existing multi-information parameters monitoring technology includes two categories: one is to set up the instrument independently for monitoring a specific physical parameters according to the needs, so as to realize the comprehensive integration of multi-physical-parameters in the landslides. This monitoring method has been widely used at present, but it requires large investment of fund, manpower and material resources. The data that obtained are low utilization rate, low accuracy and poor correlation. The other is to drill some boreholes in the sliding mass, and each borehole is integrated with instruments or sensors to monitor a variety of multi-physical-parameters, so as to realize "multiple measurements in one borehole".
It is suitable for deep slope measurement and underground water level measurement, but it is difficult to accurately measure some parameters, such as pore water pressure and moisture content. Meanwhile, the environmental adaptability of this method is poor, and the instrument inside the borehole is often damaged when the sliding mass deformation increases.

[0005]Obviously, at present, the existing technology to monitor multiple parameter outside a deep borehole into a landslide have several shortcomings. The invention can overcome existing limitations by allowing for installation of multiple sensors outside of a PVC cased borehole at any depth in the landslide.
