　　时间：8月23日

　　地点：108国道K120+600（房山蒲洼乡宝儿水村）处路侧

　　事件：山体一侧发生滑坡，方量约4000立方米

　　8月21日9时许，108国道K120+600（房山蒲洼乡宝儿水村）处路侧发生山体滑坡，滑坡土方量相当于200辆满载大货车的体积。由于公路部门提前两天发现迹象并采取断路措施，滑坡未造成人员伤亡。目前，现场仍在清理，初步预计20至30天后恢复通车。

　　滑坡或因“7·20”暴雨

　　昨日下午2时，108国道K120+600处，近1公里的道路两端，设置了警戒线，提醒“前方塌方，道路阻断”。

　　近60米高的山体一侧出现塌方，泥石混合着沙土，从山坡滚落，冲破钢丝绳防护网，在道路上积成约五十米长的泥石堆。

　　现场仍有碎石不断滑落，冲破已损坏的防护网。10多名工作人员看守，挖土车等设备停在一旁“待命”。

　　“8月19日上午11时许，巡视人员发现山体有碎石滑落在防护网上，沿安全地带爬上山顶，发现一处约1.5米的裂缝。”市交通委路政局房山公路分局局长孙波介绍，观察到山体出现滑坡迹象，并有进一步发展趋势后，房山公路分局向相关部门报告，并安排人员24小时值守。

　　20日，专家进行勘察分析，认为短时间内发生大方量山体滑坡风险巨大。当天16时30分，对该处滑坡点采取了断路措施。

　　“就在封路当天，来自河北的一行自行车队，近300人将要陆续通行事发道路。我们对车队进行劝阻，并让其劝离其他车队人员换路骑行。”北京养护集团瑞通七处谷春雷说，还好提前发现迹象并“断路”，滑坡未造成人员伤亡。

　　至于滑坡原因，谷春雷分析，“可能和‘7·20’暴雨有关。水对于破碎的山体滑动面是最不利因素。108国道时间年限已久，当时的降雨范围大，且分布均匀，可能已经把山体泡得比较饱和了，再经过一次小量降雨，就可能会形成滑坡。”

　　预计二三十天恢复通车

　　8月21日9时许，滑坡体突然发生局部滑塌，方量约4000立方米，相当于200辆满载大货车的体积，造成道路全幅阻断。滑坡顶部裂缝已由1.5米发展至5米，碎石不断滚落，不稳定山体约4万立方米，整体滑塌的险情不断加大。

　　22日，北京市交通委初步确定，采用削方、卸载、支护、锚固综合治理的处置方案。

　　“由于山体尚未稳定，泥石流还在不断持续中，我们不能贸然进行道路清理，现在约50名工作人员24小时轮流坚守。”孙波称，公路部门将全力清理现场，确保尽快恢复通车，但根据目前情况，预计还需20到30天时间。
