摘要 本文以加纳塔克拉底油气服务码头疏浚工程为例,论述在现有防波堤掩护水域内的运营码头港池且地质地形复杂的情况下,采用中微风化岩水下爆破、中微风化岩凿岩等施工工艺,利用抓斗船进行疏浚开挖,并成功运用爆破及凿岩等多项技术的典型案例。因地制宜的提供一种港池疏浚的成功案例,对类似工程具有参考意义。 This article takes the Takoradi Oil and Gas Service Terminal dredging project in Ghana as an example,to illustrate the operation techniques of underwater blasting and hammering for moderately weathered stone under the condition of complex geological terrain and in an operating terminal.It is a typical example of grab dredger used for dredging and excavation,and successfully applying multiple technologies such as blasting and hammering.Another successful case of harbor dredging is provided based on local conditions,which has reference significance for similar projects.
