抗滑桩在特高压荆门变电站边坡滑移治理中的应用

Application of Friction Pile to Control Side Slope Slippage at UHV Jingmen Substation

由于特高压荆门变电站地质土层具有膨胀性,边坡存在滑移现象,为了消除边坡滑移对道路、站区边坡及建(构)筑物的影响,经过分析、论证,采用人工挖孔钢筋混凝土抗滑桩及抗滑桩和土工格栅相结合等措施,成功解决边坡滑移的难题,确保了特高压荆门变电站工程安全、优质、如期完成。

Because the soil layer at Jingmen substation is expansive and side slope slippage occurs constantly in surrounding areas and in an attempt to avoid its adverse effects to roads, station area side slopes and buildings （structures） and via professional reasoning and analysis, artificial-digged steel-bar concrete friction pile together with the combination of friction pile and glass fiber grille has been proved to be the most suitable solution. Furthermore, it can ensure that UHV Jingmen substation project can be completed excellently and safely in schedule.
