边坡变形观测
observation of slope deformation
b ianPo bianxing guanee边坡变形观测(observation of slopedeformation)研究边坡稳定的一种主要方法,勘测阶段对边坡稳定的评价大多只能定性,通过现场监测可以搜集边坡位移速度、破坏形态等资料,有助于边坡稳定性的正确评价和精确预报。为此当建设项目确定后就需系统布置观测网,安设观测仪器,积累动态观测资料,据以确定工程处理的措施。 边坡按其组成物质可分翔贡边坡和七质边坡;据其改造程度可分自然边坡和人L边坡。由于修建工程使边坡所处环境改变的有水库库岸边坡、坝肩边坡、渠道边坡、地面厂房边坡等。边坡受地质营力作用和人类活动,可能发生各种变形破坏,如松弛张裂、滑动、崩塌、倾倒、蠕动等,威胁到工程建设的安全。 边坡变形观测可分外部观测和内部观测,前者是在变形区及其周围设立固定观测标桩,根据观测区的范围,地形条件及观测要求,组成纵横交织的导线网,并一与地区测量标志相联接,用于测定相对位移和绝对位移量。按通视条件,可采用经纬仪、水准仪、激光经纬仪等进行人工测点,观测各点的水平和垂直变位,绘制成各种成果图表。还可采用航空或地面遥感对滑坡区进行重复摄影,通过对照片上固定点的量测对比,了解边坡的变形过程。在一些变形明显的重点地段,则要设置一些位移自动记录装置及报警系统,观测相对变形速率和位移量。内部观测一般在钻孔和平洞内设置。在已查明的变形范围内选择典型的观测断面(最好与外部变形观测断面一致),进行专门的勘探,其深度应穿过变形区,达到稳定岩体内一定的深度。钻孔内布置的仪器有钻孔倾斜仪.多点位移计,挠度计、滑面计、白记地下水位仪等。平洞内可布置锢钢丝位移计、倾斜仪等。其一端埋在稳定岩体内,另一端设在变形区内。在滑动明显的平洞内,布置一些直观的简易量测装置,如横跨裂缝两侧用水泥砂浆埋设的玻璃片,观测其被拉裂、错断情况,如错开距离、方向等,并与精密仪器观测成果作对比。观测时间一般需要定期,但雨季前后、蓄水前后,库水位波动较大的时段,则应加密观测次数,及时整理、分析观测资料作出预报。(高尧基)
