插排水板堆载预压地基处理方案分析

21世纪初以来，中国滨海核电机组数量不断增多，滨海软基处理已成为滨海核电站建设面临的共性问题。某滨海核电厂为了有效解决其取水明渠防波堤滨海软基处理问题，通过技术论证和经济性分析，最终选用了插排水板堆载预压技术进行地基处理。该地基处理技术在分层堆载预压时软基的固结情况与设计基本相符，经过施工期和完工后长时间的沉降观测，沉降基本趋于稳定，插排水板堆载预压软基处理技术在此项目中的应用取得了成功，是一种经济可靠的软基处理技术，为后续滨海核电厂软基处理提供了宝贵的工程经验。

Application of Plastic Drainage Plate Combined with Surcharge Preloading: A Case Study of Water Intake Channel in a Nuclear Power Plant

According to the development of coastal nuclear plants in the 21st century, the coastal foundation treatment has been the main problem to the coastal nuclear plant construction. A coastal nuclear plant built a water intake channel on Dajin island. To ensure the rationality of technology and economy, and solve the stability problems of the coastal soft foundation, the project finally used the plastic drainage plate combined with surcharge preloading technology. After the construction period and a long time observation, the settlement is basically stable, the foundation treatment technology in the application of this project has been proved successful. And provides a valuable experience to the coastal foundation treatment.
