Paper Title:
Parameters Selection of High Pressure Consolidation Grouting for Xiaowan Resisting Force Rockmass
  Abstract

After substituting with ordinary Portland cement for geological defaults in resistance rock-masses of the dam abutments in Xiaowan hydroelectric station, it was necessary to make unsubstituted sections be reinforced by means of high pressure consolidation grouting. So it was before grouting and reinforcing that several productive experiments on high pressure consolidation grouting were carried out in the representatively and typically geological sections chosen in situ. Results indicated that desired effects for geological defaults in the dam abutments could be gotten after grouting when the distances to orifice and grouting pressures were 2m, 3m, 5~7m and 3.0MPa, 5.0MPa, 5.0MPa on the first section, the second one and the following ones of the orifice, respectively. And the grouting manners which were orifice enclosed and grout cycled in holes were adopted. Eventually, all of the grouting parameters could be used in much larger districts in projects to consolidate better.
