偏心爆破挤淤技术应用研究

Application of the Technology on Mud Displacement by Eccentric Blasting

偏心爆破挤淤法是在爆破挤淤法的基础上进行改进的一种新尝试,文中以连云港海滨新城金海一期陆域形成海堤及围堰工程为例,通过对其施工工艺介绍和设计断面稳定性验算,得出该种尝试在理论上的可行性;并对围堤工后进行钻孔检测和位移监测,进一步确定偏心爆破挤淤法在实际应用中的可行性。与传统的爆破挤淤法相比,具有节约成本,节省时间的优点,这次新尝试也可为类似工程的设计和施工提供参考。

The eccentric blasting method is a new attempt to improve the blasting method for mud displacement.Take the first phase project of Jinhai in Lianyungang new coastal city whose area structure is formed by land reclamation and cofferdam as an example,this paper introduces its construction technology and the stability of designing section,then obtains the attempt is feasible;and makes drilling detection and displacement monitoring after embankment project to further define the feasibility of eccentric blasting method in practical application.Comparing with the traditional blasting method,this method has advantages of low cost and time saving,the new attempt also can provide references for the design and construction of similar projects.
