| Abstract | The study focus ed on geological a nd geotechnical investigation for the long and deep Chi - Mun water transfer tunnel under study for implementation in Northeast Thailand. The tunnel is located in the Loei -Petchabun fold belt geologic region and passes through a complex geology of various ground conditions. Geological and geotechnical investigation data related to the project and other available data are very important key points for understanding and establishment of a clear geological model along the tunnel alignment. Geological model with geotechnical units and potential ground behavior types were evaluated based upon related information including the existing investigation data, geological mapping, boreholes data, laboratory results and additio nal investigation work. Tunnel will be excavated thr ough three rock zones which composed of low quality rocks in zone 1 (from inlet to Km. 32+831), moderate quality or fair rocks in zone 2 (Km. 32+831 to Km. 75+686), and good rocks in zone 3 (Km. 75+686 to diversion outlet) . Geological conditions are mostly of sedimentary rocks and metamorphic rocks which are consist ed of conglomerate s, sandstone, siltstone, shale, mudstone, tuff, l imestone , chert, quartzite, and slate. Moreover, igneous rocks of granite , granodiorite, diorite and some volcanic rocks are also occurred in the tunnel alignment. A number of zones of f aulted grounds are expected which are consi dered as zones of potential geohazard that might ca use difficulty in tunnelling. The identified potenti al ground behavior along the length of tunnel excavation are block falls, cave -in, running ground, water inflow and flowing ground. |
