What should the monitoring of slope be done?
First, the purpose of slope monitoring
1. The slope definition to be monitored
There are two main types of slopes to be monitored: A artificial slopes formed by the construction of human activities; B may affect the natural slopes of human activities.
2. The purpose of slope monitoring
A ensures the safety of construction personnel and machinery in the process of the formation of the slope.
The stability of the slope is determined by B after the slope is formed.
C ensures the safety of construction (structure) in the area of slope influence
Two. Standards and requirements to be mastered in slope monitoring
National norms
"Technical specification for construction slope engineering" GB50330-2013
"Specification for measurement of building deformation" JGJ8-2007
"Code for engineering survey" GB50026=2007
"Specification for identification and reinforcement of construction slope engineering" GB50843
"Standard for test method for engineering rock mass" GB/T50344
Three. The work flow of slope monitoring
1. Accept the task (usually entrusted by the owner)
2, site survey and data collection (the key geological survey, slope design, construction organization design, slope position of the meteorological information)
3, compile monitoring plan (monitoring items, monitoring purposes, monitoring methods, measuring points layout, monitoring alarm value, information feedback system, monitoring frequency and cycle).
4, laying and protection monitoring points, calibration instruments and components
5. Field test (data acquisition)
6. Analysis and collation of monitoring data and feedback
7. Submission of phased results and reports
8. Submit the monitoring summary report after the completion of the project monitoring
Four. The content of slope monitoring
The horizontal and vertical displacement of supporting structure, the top or the supporting structure variable quantity at
The surface crack, the top 1.08 behind (rock) 1.58 (soil) range
The top building (structure) ne deformation, wall foundation, and the overall tilt slope of buildings
The relationship between rainfall, flood and time
Anchor (case) pulling force, external anchor head or main bar of storage rod
Deformation of support structure, main force member
The supporting structure stress, maximum stress
The relationship between groundwater, water seepage and precipitation, water outlet point
Five. The compilation of monitoring program
The content of the monitoring programme should include:
Engineering survey
Geological and geotechnical conditions and surrounding environment conditions
The purpose and basis of monitoring
Content and project of monitoring
Layout and protection of datum point and monitoring point
Methods and accuracy of monitoring
Monitoring time and frequency
Monitoring and alarm and abnormal monitoring
Monitoring data processing and information feedback
The staffing of the monitoring staff
Monitoring equipment and verification
Operational safety and other management systems
Seven. Monitoring Report
1. The general situation of slope engineering
2. Monitoring basis
3. Monitoring instruments
4. The layout of the measuring point
5. The mileage curve of monitoring project index
6. Monitoring data arrangement, analysis and results review
