The technical method of accurately determining bore - hole trajectory using common surveying instrument 应用普通测斜仪精确确定钻孔空间轨迹的技术方法
On the basis of an all - around analysis typical areas were selected to carry out the deformation monitoring . the monitoring depth formulation is modified 本文在对实地勘查资料进行全面分析的基础上，选择码头的典型区域进行深层位移监测，修正了常规测斜仪监测深度公式。
Calculating adopts the way of finite unit spot parameter by using the character of dispersion . thus , it can get the similar answer of stress , stress strain and displacement . supervising uses strainmeters , non - stressmeters and tiltmeters , which are buried in the concrete wall to supervise the stress , tress strain , displacement during period of working and makes the forecast 计算采用有限元法将混凝土防渗墙利用离散化变为有限单元节点参数，从而得到应力、应变、位移的近似解；监测采用应变计、无应力计及测斜仪现场埋设在砼墙体内对混凝土防渗墙在施工期及运行过程中进行监测其应力、应变、位移，从而作出预报。
