What should slope monitoring do?

First, the purpose of slope monitoring

1, to monitor the slope definition

There are two main type of slope to be monitored: a artificial slope for by that construction of human activities; B natural slopes that may affect human activity.

2, the purpose of slope monitoring

A to ensure the safety of construction personnel and machinery in the process of slope formation;

B, judging the stability of the side slope after the side slope is formed;

C to ensure the safety of the building ( structure ) within the scope of the influence of slope

Two, slope monitoring must grasp the norms and requirements

National norms

Technical specification for building slope engineering GB 50330 - 2013

Code for measurement of building deformation jgj 8 - 2007

Code for engineering survey GB 50026 = 2007

Technical specification for evaluation and reinforcement of building slope engineering GB 50843

Standard for test methods of engineering rock mass GB / t 50344

National industry standards:

Local regulations

Iii. workflow of slope monitoring

1, accept the task ( generally to the owner commissioned )

2, on-site reconnaissance and collection of data ( the key is geological survey, slope design, construction organization design, slope location of meteorological data, etc. )

3, the preparation of monitoring scheme ( monitoring project, monitoring purpose, monitoring method, measuring point layout, monitoring items of alarm value, information feedback system, monitoring frequency and cycle )

4, embedding and protection monitoring points, instruments and components calibration

5. field test ( data acquisition )

6, analysis and collation of monitoring data and feedback

7, submit periodic results and reports

8, after the completion of the project monitoring to submit monitoring summary report

Four, the content of the slope monitoring

V monitoring programme development

Monitoring programmes should include:

Engineering survey

Geological and geotechnical conditions and surrounding environmental conditions

Purpose and basis of monitoring

Contents and items of monitoring

Layout and protection of datum points and monitoring points

Monitoring methods and accuracy

Monitoring time and frequency

Monitoring alarm and abnormal situation monitoring

Monitoring data processing and information feedback

Monitoring staffing

Monitoring equipment and verification

Operation safety and other management systems

Vii. monitoring reports

1, slope engineering survey

2. monitoring basis

3, monitoring instrument

4, measuring point layout

5. mileage curve of monitoring project indicators

6, monitoring data sorting, analysis, results review
