| 摘 要： | 福建LNG输气干线漳州段ZZ034G+2号桩附近由于国道加宽开挖，形成了人工高陡边坡。受雨季及不良地质条件影响，该边坡已出现部分滑塌，边坡顶部出现较宽的张性裂缝，严重威胁到边坡顶部天然气管道的安全运营。根据工程地质条件及勘探成果，该边坡被分为两段进行治理。采取了土方反压、抗滑桩、锚索、格构梁及挡土墙等多种加固措施，设置了截排水沟及泄水孔等排水措施，采用了信息化施工及边坡监测技术，取得了良好的边坡治理效果。

| Abstract: | Due to a national highway widening excavation was carried out near the pile ZZ034G 2 of Zhangzhou section of Fujian LNG gas transportation trunk line, an artificial high and steep slope was formed there; and the slope was partially collapsed and a wide extensional crack appeared at the top of the slope for the impact of rainy season and poor geological conditions, which was a serious threat to the safe operation of the gas pipeline at that place. According to the engineering geological conditions and exploration results, the slope treatment was divided into two sections. A variety of reinforcement measures of earthwork backpressure, anti-slide pile, anchor, lattice beams and retaining wall were taken for the slope treatment, interception ditch and drainage hole were set and information construction and slope monitoring technology were adopted with good effects in slope treatment. |
