DESCRIPTION OF PROJECT:

The slope failure in Northern Thailand is often occurred particularly in Maehongsorn province. Department of Highway (DOH) intends to improve the remedial slope failure methodology. The monitoring data is used to assess the remedial methodology during construction and long term performance. The results of the monitoring will be justified how the further remedial work can prolong the longevity or provide the early warning of impending and/or critical failure. International Engineering Consultants Co.,Ltd (IEC) awarded contract to carried out the geotechnical instrumentation work to monitored the remedial slope performance in term of ground movement, pore water pressure and also surface settlement. Interpretation and analysis using geotechnical finite element program were carried out.

SCOPE OF SERVICES:

• Supplied and installed the following instruments:

• Inclinometer, to monitor magnitude and rate of ground movement in lateral direction.

• Pneumatic Piezometer, to assess the insitu pore pressure distribution.

• Vibrating wire liquid settlement, to monitor rate of settlement.

• Total pressure cell, to monitor pressure occurred due to fill embankment.

• Observation well, to monitored ground water level

• Surface settlement plate, to monitor surface settlement.

• Monitoring work and interpretation report

• Analysis the instrumentation results and prediction using geotechnical Finite element program.

• Evaluation of remedial slope performance during construction and long term performance of remedial slope.

KEY FACTORS:

• The data is used to verify the design assumptions and to check that performance is as predicted

• The monitoring results are assessed how the construction can proceed without risk of failure and perform proper function in long term period.

• The monitoring results provide the early warning of impending and/or critical failure,

• Improve the remedial methodology.
