结合达万线分水寺隧道内承力索腕臂安装工程，讨论了从隧道口至隧道内780m处温度变化及承力索伸缩情况，分析并计算了该区段范围内各悬挂点的腕臂偏移量，得出结论，在长大隧道靠近隧道口区段内气温变化与距隧道口的距离呈非线性变化关系，各段承力索伸缩量也呈非线性变化关系。

With reference of messenger wire cantilever installation inside Fenshuisi tunnel on Dazhou-Wanzhou line, it discusses the variations of temperatures and the expansion of messenger wires within a section from the entrance of the tunnel to point of 780 m inside tunnel, analyzes and calculates the offset values of the cantilevers on all suspension points inside this section, and the conclusion is obtained that the temperatures at the points along the section adjacent to the entrance of the tunnel will be in non-linear variations, and the expansion length of the messenger wires will be in non-linear variations as well
