摘要
介绍微型抗滑桩对通平高速公路k38+560～k38+680高边坡加固工程。根据该边坡的稳定系数和剩余下滑力,设计微型桩直径300 mm,长10～14 m,同排桩间距2 m,前后桩间距0.8 m。工后应力监测的桩身应力分布和前后桩应力结果,与理论分析结果比较接近。本工程微型抗滑桩加固设计和监测结果对以后类似工程具有重要的意义和指导作用。
The reinforcement research has been adopted in the Tong-Ping highway k38＋560~k38＋680 high slope by the ＂door＂ miniature anti-slide piles.The slope stability coefficient and remaining down-slide stress have been gain by calculation.The diameter of the ＂door＂ miniature anti-slide piles is 300 mm,their length is 10~14 m,the spacing between the left and the right piles is 2 m,the spacing between the before and the after piles is 0.8 m,The pile body stress monitoring has been done,the pile body stress distribution and the pile stress are much closer to the theoretical analysis results.The miniature anti-slide pile reinforcement design and the monitoring results are important significance and guiding role to the after similar projects.
