The Key Influence Factors Analysis in Soft Ground Improvement About a Nuclear Power Plant

Abstract

Study on the diameter and the arrangement of rock-socketed piles in soft ground improvement is of great important influence factors for the seismic safety evaluation of nuclear power plant. Combined with a proposed nuclear power plant structure engineering project, according to the actual situation, the influencing factor of the rock-socketed piles diameter and the arrangement of rock-socketed piles are compared and analyzed. The influence law of the seismic response of the nuclear power plant structure is obtained. In the analysis process, we use the method of numerical simulation to establish rock-socketed pile-soil-structure dynamic interaction of nuclear island under the condition of soft soil foundation calculation model. The experience and conclusions can be for reference under the similar conditions for the optimization design of rock-socketed piles in the soft soil.
