重力式码头基床爆夯质量控制与安全控制

CONTROL OF QUALITY AND SAFETY IN EXPLOSIVE COMPACTION OF FOUNDATION BED FOR GRAVITY TERMINAL

在重力式码头基床密实的施工中经常采用爆炸夯实。尤其在水深和基床厚度比较大的情况下 ,爆夯比传统的锤夯具有更明显的优势。然而 ,爆夯施工对周边环境影响较大的问题成了制约爆夯技术应用和发展的重要因素。如何解决爆夯质量控制与安全方面的矛盾 ,是爆夯施工管理面临的课题。本文结合厦门嵩屿港区 1 # 泊位基床爆夯工作的实践 ,对爆夯质量控制与安全控制的问题进行了初步探讨。

Explosive compaction is usually used in compaction construction of foundation bed for gravity terminal.As compared with traditional hammer compaction,the explosive compaction has further remarkable advantages,especially in the case of deeper water and thicker foundation bed.With extensive use of explosive compaction,the problem of which the harmful effects induced in explosive compaction have larger affection to the surroundings has become an important factor in restriction of its application.How to solve the contradiction between control of quality and safety is a problem in the management of explosive compaction.In this paper,an approach to the problem is made based on the practice of explosive compaction of foundation bed in the project of Songyu Port Berth No.1 in Xiamen.
