Introduction

In order to improve the level of collapse, landslide deformation monitoring and debris flow monitoring, and to standardize monitoring behavior, this code is formulated.

This code was drafted in 1994 and has been tried out in the geological disaster prevention and control project in the Three Gorges Reservoir area, and has been revised this time.

Specifications for monitoring collapse, landslide, and debris flow

1 Scope

This code specifies the monitoring content, monitoring methods, monitoring point network layout, and monitoring data collation of landslide, collapse deformation and debris flow activities.

And technical requirements such as deformation and damage or activity prediction.

This code is applicable to the monitoring of landslides, avalanches and mudslides that have occurred and may continue or reoccur in deformation, destruction and activities.

And monitoring of natural or artificial slopes and mud-rock flow active trenches (or slopes) that are likely to collapse.

This specification focuses on professional monitoring, and part of the content is available for group testing and group defense monitoring.
