中文摘要：
河北省宽城县遵（化）—小（寺沟）铁路穿越一个体积约77×104m3的古滑坡体,因在滑坡前缘以路堑方式穿过,开挖施工导致古滑坡复活。为保障未来铁路的运营安全,需要对其进行彻底治理。在现场地质调查及试验,以及分别对沿复活滑坡体新滑面和古滑面在不同工况下的稳定性计算的基础上,结合复活滑坡体的具体特征,提出2种治理方案,即＂抗滑桩＂方案和＂削方＋抗滑桩＋桩间挡土墙＂方案。通过综合比选确定后者为采用方案,并具体进行了削方、抗滑桩、截排水系统和坡面防护等设计。
英文摘要：
In Kuan-cheng county of Hebei province,a railway to be built will cut across an ancient landslide mass of about 77×104m3,and in the form of a cutting channel in front of the ancient landslide mass.Excavation of the cutt slope in the mass could lead to re-activity of the ancient landslide.To ensure the safety of railway operation in the future,a complete treatment is necessary.Based on geological survey in the field and experiment,the stability of the ancient landslide mass is calculated along the existing and ancient sliding surface with different working conditions and combining with specific characteristics of the revival landslide.Two treatment schemes were put forward.They are the ＂anti-slide pile＂ scheme and the ＂cleanup＋earthwork＋anti-slide pile＋retaining wall between piles＂ scheme.Through an integrated comparison,the second scheme was adopted and completed.Works include cleanup earthwork,anti-slide piles,drainage system,and slope protection.
