摘要(Abstract)：

介绍了沪(上海)杭(州)甬(宁波)高速公路既有线大方量、高边坡扩堑深孔水压控制爆破设计与施工,重点介绍了深孔水压爆破炮孔装药结构、无隔墙无侧向排架防护的施工方法,以及所取得的技术成果和产生的经济与社会效益,为类似工程提供了成功的经验。
The design and construction of mass volume high side slope cutting expansion of Hu-Hang-Yong highway,an existing one starting from Shanghai(Hu)through Hangzhou(Hang)to Ningbo(Yong),by deep hole water-pressure controlled blasting was introduced by focusing on the discussion of charging structure of borehole of deep hole water-pressure blasting,construction method of none-partition wall and none-lateral rack protection and achieved technological achievements plus their economic and social benefits.The present paper offered successful experience for similar engineering in the future.
