摘　　要：宁德核电厂厂区护岸工程是核电厂防御海潮及海浪袭击的重要屏障,针对该工程位置处淤泥层厚,斜坡堤压脚平台宽的特点,在采用常规爆破排淤填石法不能形成设计断面情况下,采用控制加载爆炸挤淤置换法完成了设计断面的实施,该方法的应用能够对深厚淤泥层地质处的地基进行置换处理,使宽压脚平台的爆破实施成为可行,为同类工程提供了成功经验。The revetments for Ningde Nuclear Power Plant are an important shelter for the plant to guard against sea tides and waves. Since the silty stratum was great in the location where the revetments are to build and the apron bermes for the revetments were wide, it was impossible to form a design cross section by using the conventional method of displacement by blasting with rock fill. Hence, the method of displacement by blasting with controlled loading to remove the silty soil was adopted to achieve the design cross section. The method can not only displace the deep and thick silty soil with replacement but also make it practicable to build a wide apron berme by blasting, offering successful experience for similar projects.
