爆炸挤淤置换法地基处理海堤结构结合滨海公路开发的特点及工程实例

Base Treatment of Seawall Structure by Blasting Squeezing Displacement Method Based on Development Characteristics and Engineering Practice of Coastal Highway

滨海公路建设在海堤上,往往存在路面宽度窄、路基高度较高、地基沉降量大、安全性不足的问题,因此选择合适的海堤结构形式,是十分必要的。分析了采用爆炸挤淤置换法进行地基处理的海堤结构的特点,总结此种路基处理方法满足临海公路功能的作用,并将爆炸挤淤置换法应用于双剑涂围涂工程,取得了良好的效果,为类似工程提供参考依据。

There are often problems of narrow width of pavement, higher roadbed height, large subgrade settlement and insufficient safety when the coast highways are constructed on the seawall. Therefore, it is very essential to select a suitable type of seawall structure. The article analyzes the characteristics of using the blasting squeezing displacement method to treat the base of seawall structure, summarizes this roadbed treatment method satisfying the function of coast highway, and introduces the application of the blasting squeezing displacement method in Shuangjiantu Sea-closure Project with the good effect, which can be referenced for the similar projects.
