摘　　要：缆索广泛用于大跨度桥梁和大型建筑结构,主要有:平行钢丝预制索股和吊索用于悬索桥,斜拉索用于斜拉桥,拉索用于大型建筑结构等。缆索由索股(钢丝、钢绞线、钢丝绳)和锚具构成,合金热铸锚是主要锚固方法之一。介绍缆索用热铸锚锚具和灌铸的现状,分析工程应用中存在的问题,提出一些相关改进措施。Cables are widely used for long-span bridges and large building structures. Of the cables, the prefabricated parallel wire strands and suspenders are used for suspension bridge, the stay cables used for cable-stayed bridge and also for large building structures. Normally, a cable system is composed of steel wires, strands or wire ropes and anchor sockets, and one of the anchor devices for the cable is the hot-cast alloy socket. In this paper, the state-of-the-art of the hot-cast alloy sockets and the perfusing procedures for the sockets are presented, their problems in the practical applications are analyzed, and related improvements are proposed.
