| Abstract: | High pressure jet grouting piles were adopted in sluice foundation treatment work of Shanxi Pingtou Hydropower Station Project for foundation reinforcement. Several on-site production tests were conducted for studying the pile diameter problems in silty clay layer, appropriate spin spray parameters and construction techniques are finally determined to improve foundation bearing capacity of the clay soil layer, shorten the construction period, and save investment, thereby providing successful example for solving other similar projects. |
