钢绞线挤压锚固夹持结构的优化研究

该研究主要是为解决产品的优化升级,同时为满足一些对锚头外露量有限高要求的特殊吊索而设计的锚具结构。通过对锚头结构的优化设计,在满足其可靠的锚固性能的同时,又可以实现产品的成本节约、提高生产质量,甚至可以提升拉索满足高应力幅受力状态下的承载要求,另外也可以解决拉索在拱桥吊杆中的特殊工程需求。

Discussion of Construction Related to Sheet-piled Wharf

In this paper, firstly, the characteristics of sheet-piled wharf construction are introduced. And then, six aspects of sheet-piled wharf construction are discussed： sheet pile, anchorage structure, guiding girder, anchor rod, backfilling behind sheet pile wall, superstructure of sheet-piled wharf etc. The construction of sheet pile involves piling on the land or piling？on？the sea, piling methods, piling patterns, guide frame, embedding sheet piles etc.
