摘要
Because of the rich water content and high water level,the safety would be influenced in the foundation pit construction for a building in Nanyang City and the main difficulty was dewatering. The construction safety was ensured depending on the strict foundation pit support and dewatering scheme. The paper introduces the application of the design of shotcrete & rock bolt support and dewatering as well as the construction process.
