中文摘要：

针对某钨矿须在滑坡体上建设台阶式重载厂房的问题,基于选厂建设与滑坡治理相结合的思路,利用4排悬臂式抗滑桩作为滑体支挡结构,同时兼做选厂内台阶挡土墙基础和选厂厂房基础,充分发挥承载抗滑桩阻滑和承重的双重作用,提出台阶式重载厂房下滑坡体治理优化设计方法。依据传递系数法推导得出考虑上部厂房荷载条件下多排承载抗滑桩抗力分配计算方法,并在此基础上进行钨选厂滑坡推力分配计算和承载抗滑桩结构优化设计研究。有限元法计算结果和基于本文优化设计方案的滑坡体长期监测数据,验证了多排承载抗滑桩抗力分配计算方法和该钨矿滑坡体治理优化设计方法的合理性和适用性。针对现行规范在多排承载抗滑桩抗力分配计算方法上的空白,提出了相应的补充意见。为保证滑坡体上部厂房长期稳定前提下进行滑坡体治理提供了有益的设计思路,也为类似工程的滑坡体治理和厂房等建筑物建设提供了借鉴和参考。

英文摘要：

The stepped overloaded plants were needed to be built on a landslide slope for a tungsten mine. Four rows of anti-slide piles were proposed for the treatment of sliding mass as well as the foundation of intra-plant step retaining wall and plants. In this case,the dual function of load-bearing and anti-slide could be utilized for the load-bearing and anti-slide piles. The optimization design and treatment methods for landslide under stepped overloaded plants were presented. Based on the transmit-coefficient method,an approach of resistance distribution of multi-row load-bearing and anti-slide pile was proposed considering the upper plant loads. With this method,the distributions of multi-row piles at the tungsten ore plant were calculated,and then the optimized design of load-bearing and anti-slide piles were conducted. Finally,with the long-term monitoring data of the landslide and the calculation results from finite element method,the rationality of the proposed method for the resistance distribution of multi-row pile was validated,and the applicability of the optimized design method for landslide treatment was verified. According to the inadequacies of resistance distribution of multi-row load-bearing and anti-slide pile in the current specifications,corresponding supplementary suggestions were proposed in this paper.
