Determination method for deep horizontal displacement by taking inclinometer orifice as benchmark
The invention discloses a method for determining deep horizontal displacement by taking an inclinometer orifice as a reference, which comprises the following steps of: establishing a plane-coordinate system, and installing an orifice coordinate measuring device; observing the initial coordinates of each measuring point orifice through a total station; determining the horizontal displacement increment of each measuring point at different depths through an inclinometer; determining the horizontal displacement of each measuring point at different depths by taking the initial coordinates of the inclinometer pipe orifice at the measuring points as a reference; determining the corrected horizontal displacement of each measuring point at different depths according to the displacement of the inclinometer orifice; and determining single and accumulated horizontal displacement variations of different depths of each measuring point. The inclinometer orifice coordinate measuring device has the advantages that the inclinometer orifice coordinate measuring device is convenient to install, the principle is simple, position coordinates of an inclinometer orifice at different time in the foundation pit excavation process can be accurately reflected, errors caused by the fact that horizontal displacement at different depths of all measuring points of a supporting structure cannot be corrected when the pipe bottom of the inclinometer is used as the reference are eliminated, and the measuring accuracy is improved. The accuracy of monitoring data is improved, and powerful support is provided for evaluating the safety of the foundation pit.
本发明公开了一种以测斜管孔口为基准的深层水平位移确定方法,建立平面坐标系，安装孔口坐标测量装置；通过全站仪观测各测点孔口初始坐标；通过测斜仪确定各测点不同深度的水平位移增量；以测点测斜管孔口初始坐标为基准，确定各测点不同深度的水平位移量；依据测斜管孔口位移量确定各测点不同深度的修正水平位移量；确定各测点不同深度的单次和累积水平位移变化量。本发明优点在于测斜管孔口坐标测量装置安装方便、原理简明，能准确反应测斜管孔口在基坑开挖过程中不同时间的位置坐标，消除了以测斜管管底为基准时无法修正支护结构各测点不同深度处水平位移量而引起的误差，提高了监测数据的准确性，为评价基坑安全提供了有力支撑。
