Abstract

Slope failure due to slope instability can initiate landslides whichmay result in loss of lives, property, infrastructures and economicloss. There are many factors that trigger slope failure such asrainfall, hydrological condition, groundwater level and geologicalformation of the slope area. However, slope failures can beprevented by monitoring high risk slopes using geotechnicalinstruments and electronic sensors. In this study, an early warningsystem was developed to immediately alert the authority and themanagement on slope stability by installing selected slopemonitoring instruments at high risk slopes with infrastructures.Slope monitoring system using wireless network is an effectivemethod to monitor the condition of slopes especially theinaccessible slopes in unsafe areas. By applying this system, themanagement can reduce cost, human resources and time onslope maintenance that can efficiently notify themaintenance team on potential unsafe slopes or slope failures

Abstract

This paper describes a virtual geo-hazard monitoring and assetmanagement system (ViGMAS) which implements a near realtimesatellite image processing system to extract relevantenvironmental and meteorological parameters. The systemfocuses on geo-hazard monitoring by accumulating informationabout the earth using remote sensing technologies which can beapplied in disaster risk management. This system also includesasset management program for managing assets by inventoryand assessment through integration with Geographic InformationSystem (GIS). Mapping and inventory by GIS help to improveefficiencies and assist in decision making based on gathereddata. The system was designed to manage preliminaryconstruction and management planning, health performance, riskand costs of management asset through 4D visualization whichintegrates existing data and primary data obtained from a dataset of mapping terrain and satellite that will fit in the system ofvirtual reality

Abstract

The problems of slope instability can be related to the terrainfactors and weather. In Malaysia, slope failures and landslidesare very common due to prolonged monsoon rainfalls. Theconsequences of slope instability can be hazardous to lifeincluding economic damages and costly repairs. The study wasaimed to determine the physical and mechanical properties ofthe rock slope material from selected sites. Several testsincluding field observations were performed to analyze theengineering characteristic and physical properties of this Schistrock slope and Granite rock slope. The rock samples wereclassified into various weathering grades based on variations inthese properties. Scan line methods were applied to obtain themeasurement data. Direct discontinuity surveys were carried outin interval of 10 m. Laboratory tests on the samples were donethat include two cycles of slake durability, Schmidt hammer test,point load test, petrography test, density test and direct shearbox test. The analysis on each rock types showed that theamphibolite Schist at Putrajaya has the highest rock strengthwith a uniaxial compressive strength (UCS) 487.97 Mpa which isclassified as extremely strong rock. By comparison, the UCSvalue of Granite was 267.28MPa and classified as strong rock
