高速公路高边坡施工安全监测
Time:2017-03-22 Views:
1)为了确保施工期的安全施工,应进行安全监测。监测的部位包括开挖结构面和开口线上部岩体,通过人工巡视检查和对观测数据进行整理、分析,掌握边坡岩体内部作用力和外部变形情况,评估和判断高边坡的稳定状况。
2)施工期巡视检查:
定期进行边坡的巡视检查工作,检查内容包括边坡是否出现裂缝,以及裂缝的变化情况(裂缝的深度及宽度)、是否出现掉渣或掉块现象,坡表有无隆起或下陷,排、截水沟是否通畅,渗水量及水质是否正常等,并做好巡视记录。
3)边坡外部变形监测:
在边坡重点部位,布置变形观测墩,施工期的变形观测应结合永久观测进行。通过大地测量法监测边坡变形情况,包括平面变形测量和高程变形测量。有条件的宜采用较为先进的全球定位(GPS)变形测量系统。
4)表面裂缝监测:
主要监测断层、裂隙和层面的变化情况,通过在边坡裂缝表面安装埋设监测仪器,来反映边坡裂缝的开合情况。
5)深层变形监测:
通过在边坡内部深层安装埋设监测仪器,来反映边坡内部变形情况。主要采用测斜仪、多点位移计、滑动测微计等。
6)支护效应监测:
主要是对锚杆、锚索应力监测,通过在典型部位锚杆、锚索上安装监测仪器,对锚杆、锚索的应力进行监测,反应锚杆及锚索的支护情况及支护效果。主要采用锚杆应力计及锚索测力计进行监测。
7)爆破振动及声波测试:
在边坡开挖过程中,由于爆破震动影响,有可能造成边坡失稳,通过
爆破振动监测
及声波测试以控制爆破规模。采用设备宜为:爆破振动测试记录仪、声波仪等。
8)边坡渗流监测:
通过对地下水位和渗流量的变化情况来判断边坡的稳定状态。采用的设备为渗压计及测压管等。
9)应做好边坡施工安全监测成果的整理、反馈工作,以指导施工,边坡的变形数据的处理分析,是边坡监测数据管理系统中一个重要内容,用于对边坡未来的状况进行预报、预警,并对边坡的稳定现状进行科学的评价,预测可能出现的边坡破坏,应做好边坡施工安全监测成果的整理、反馈工作,以指导施工。
