Default 登山自救知识

1.一手抓住冰镐头部,拇指在镐尾上,其它手指在镐锋上自救抓握法;另一手握住冰镐柄尖头以上的位置。两手 均握紧。
2.镐锋在肩部上方位置压入山坡,冰镐柄成对角线斜过胸前方,贴着另一侧髋部握紧,盟特。冰镐柄较短时以同样的姿势握住,虽然冰镐柄尖头到不了另侧髋部。
3.胸和肩紧压镐柄,脊柱弓起,稍离雪面。背部弓起至关重要:它把登山者的重量置于镐锋和脚趾(或膝盖)上 ,光波炉菜谱,即抠入雪中实现控制的那些点上,形成弓形的最佳方式是集中精力拽住镐柄的末端,镐柄较短会更困难。这种拉 力形成弓形并使重量移向镐锋那边的肩膀,光波炉。注意:那些不愿使胸和脸没入雪中的人可能会使背部弓起过高。
4.两腿挺直,分开,脚趾抠入雪中(如果穿钉鞋,使脚趾离开雪面直到最后几乎停住),盟特新奇特加盟
5.紧握冰镐。紧握冰镐头部会使镐锋挨着肩部和颈部。另一只手必须靠近镐柄的末端以防止镐柄尖头为轴心转入 大腿,造成重伤。尤其在松软的雪上,挺直分开的两腿以及抠入雪中的脚趾可增加阻力,加大稳定性,在硬雪或冰 上并穿着钉鞋时,两脚必须抬离山坡直到速度减慢,这样鞋钉就不会止住登山者并把他向后抛去。双膝可帮助下滑 者保持稳定但在硬雪或冰上却无法让他停住,尤其是当他正好穿着光滑的防风裤时。
好的自救姿势可能会非常优美,但是在实践中,即刻实施是极其关键的。停止下滑所需的可能仅仅是一个蹩脚但迅 速的控制。过分关心姿态的优美会导致行动迟缓,从而使下滑增加到一个完美姿态也无法制止的速度。关键在于尽 可能用力而迅速地刺入镐锋。
