某天然气井场填方滑坡治理过程分析及效果评价

Analysis on the Process of Fill Landslide Treatment in a Natural Gas Well Site and the Effect Evaluation

某天然气井场坐落于一填方平台,由于土体填方施工时未达固结,致使该天然气井场3次发生滑坡灾害,并3次进行治理。采用的治理方案依次为地面排水+注浆加固+抗滑桩、抗滑桩+挡土墙加固、微型组合抗滑桩。在阐述该天然气井场填方滑坡特点的基础上,对治理工程及其效果进行了分析。

A gas well site is located in a fill platform, the landslide disaster occurred for 3 times, because the soil filling was not consolidated when the construction was started.The treatment solutions for 3 landslides were ground drainage +grouting reinforcement +anti-slide pile, the anti-slide pile +retaining wall reinforcement and micro combination anti-slide pile.Based on the characteristics of landslide in the natural gas well fill, the treatment engineering and the effects are analyzed, and the action effects of micro combination anti-slide pile technology used in this landslide treatment is especially analyzed.
