| Abstract: | Water inrushes occurred several times in Malujing tunnel,such as 1.21and 4.11 water inrush accidents.In order to investigate the scale of karst water in a cavity,parallel heading detection was performed in the early stage at tunnel exit.In the later stage supplemental geological prospecting and strengthened predictions were carried out.By means of TSP203,IR detection,geological radar,advance boreholes and exploration technologies,the area and boundary of cavity were accurately located,and the properties of ... |
