| 摘 要： | 位于四川省巴中市城南1km处的南龛斜坡变形不断发展扩大，一旦失稳破坏，损失无法估量，必须进行工程治理。文章在深入研究南龛斜坡变形破坏特征、成因机制、主导诱发因素及稳定性的基础上，针对斜坡变形体辩证施治，拟定由抗滑桩工程、地表排水工程、防渗和生物工程等4个部分组成综合治理系统，布置于变形破坏强烈的重点灾害地段，以控制斜坡变形发展，根除危害。为此，作者拟定出不同抗滑工程组合方案，分别从治理的安全可靠性、技术可行性、经济合理性方面进一步优化，制订出了对变形破坏极强烈段布设2排抗滑桩工程，再结合地表排水、地面防渗和生物工程等综合治理方案，完成治理工程设计。该变形体治理工程总投资231．83万元，可以保护价值l亿元的建筑物和各种设施、7000余人的人身安全，社会效益、经济效益、环境效益十分显著。 |

| Abstract: | Nankan slope deformation body locates at 1 kilometer south of Bazhong City in Sichuan Province. The trend of its deformation and failure is gradually expediting. The loss of property will be great once the deformation slope fall into failure. Based on the detailed studying of the deformation and failure characteristics, the de formation mechanism, the main triggers and the stability of Nankan deformation slope, the paper puts forward a suit of control measures, including slide-resistance piles, ground surface drainage, seepage-resistance projects and biological projects, to control the deformation of slope. The controlling system composed of the mentioned measures should be disposed in the section of strong deformation and failure in order to control the developing of slope deformation and failure. In view of security, technical feasibility and economic rationality of the controlling measures, the authors optimize the design project of the controlling system. Combined with ground surface drainage, seepage-resistance projects and biological projects, two rows of slide-resistance piles are set in the section of strong deformation slope. The total investment of the controlling system is only DY-2.32 millions. The total value of the properties which are protected by the controlling measures cost about DY-100 millions. There are about 7000 peoples are safeguarded by the controlling system. |
