摘要
在湘粤山区仁新高速公路施工中,因连续强降雨浸泡山体覆盖层造成原有地貌受力改变,坪田隧道进口右洞与斜井之间的扇形体存在滑坡安全隐患。为消除滑坡隐患,决定对此隧道陡坡洞口的复合式扇体变形山体进行抗滑桩加固处理;从施工安全角度出发,抗滑桩施工采用静态爆破技术,并对其工艺原理及技术要点进行研究分析,为其应用的范围扩大总结经验和参数,为今后类似工程提供借鉴。
In the Hunan mountainRenxin highway construction,due to continuous heavy rain soaked mountain cover caused by the existing topography force change segment between tsubota tunnel right hole and shaft are imported landslide safety hazards. In order to eliminate the hidden dangers of landslides,decided this steep slope tunnel hole composite fan body deformation of anti slide pile slope reinforcement;from the perspective of construction safety,construction of anti slide pile by static blasting technology,and the process principle and key technology research and analysis,summarize the experience and expand the application range of the parameters for reference. For similar projects in the future.
