三代核电EPR(Europe Pressure Reactor)重要厂用水廊道工程,原方案要求将廊道底板至微风化岩范围内全部回填素混凝土.后经分析论证,采用级配碎石代替素混凝土回填、保留强风化岩和中风化岩的方案,该方案技术可行,已成功应用于廊道工程,节省了大量投资.%The original scheme of important water gallery of Europe Pressure Reactor (EPR) New Power Station requires to backfill plain concrete within the full scope from the gallery bottom slab to the slightly weathered granite. After analytical demonstration, a new scheme is adopted that replacing plain concrete by graded hroken stone for backfill and reserving the strong weathered granite and medium weathered granite. This scheme has technical feasibility and has been successfully used in gallery engineering to obviously reduce investment.
