This project has established a new generation of DPM based methodology for objective, efficient, continuous and accurate testing and evaluation of in-situ strength and quality profiles of geo-masses in ground. The DPM technique includes a hardware system for in-situ automatic monitoring and recording of drilling parameters in real time sequence and a software package for analyzing and presenting the digital data in time series.
DPM system can provide good knowledge of mechanical behavior of soil and rocks and their spatial variability to help the design and construction of geotechnical works including foundations, slope stability and tunnels. It can give us additional and factual data about the ground conditions to have better landslide hazard prevention in Hong Kong and Mainland China. DPM was the core technique/idea for winning further research grant of HK$7,382,020 from other sources in Hong Kong and Mainland China.
