基坑的开挖和支护是当前水利工程安全施工中的重要问题。该研究以江苏省宿迁市船行二站拆建工程深基坑开挖工程为研究对象,采用每2m一层的开挖步长,南北侧设置钻孔灌注桩加一道锚索张拉,同时采用施打钢板桩的支护方案,利用有限元软件对... 基坑的开挖和支护是当前水利工程安全施工中的重要问题。该研究以江苏省宿迁市船行二站拆建工程深基坑开挖工程为研究对象,采用每2m一层的开挖步长,南北侧设置钻孔灌注桩加一道锚索张拉,同时采用施打钢板桩的支护方案,利用有限元软件对其开挖和支护进行模拟。模拟结果表明,在基坑的开挖过程中,基坑开挖面由于上部荷载的释放会产生地面反弹,基坑中心反弹量最大;基坑坡面整体向基坑内侧方向变形,混凝土灌注桩顶部向基坑外侧方向变形,底部向基坑内侧方向变形,但变形量较小,从而证明采用的加固措施方法是有效的。 展开更多

The paper identifies twelve elements of ship recycling recycling system. The source and items of knowledgebase for ship and highlights their respective roles and duties in a proposed ship recycling have been brought out. A new philosophy focusing clean and safe ship recycling namely design for ship recycling has been introduced based on principles such as ecofriendliness, engineering efficiency, energy conservation and ergonomics. The role of naval architects in ship recycling industry has been described based on the above factors. The paper brings out the role of naval architects in ship recycling the way it has been practiced worldwide and proposed by regulatory bodies. The authors have brought out the new concept of design for ship recycling and various aspects of it. The role of naval architects in the practice of this new design philosophy which is ready to be embraced by the maritime industry has been reiterated. 展开更多
