The invention provides a foundation pit support pile horizontal displacement measurement method and device. The foundation pit support pile horizontal displacement measurement method comprises the steps that a measurement face is marked at the interval of a length unit in the length direction of a metal rod; four strain gages are arranged on each measurement face in a surrounding and attached manner, wherein every four strain gages are uniformly distributed in a spaced manner; the metal rod is arranged in a foundation pit support pile in a buried manner, wherein the top end of the metal rod isexposed to the upper surface of the foundation pit support pile; the horizontal displacement and rotation angle of the top end of the metal rod are monitored, and the strain of each strain gage is collected; and the horizontal displacement of each measurement face on the metal rod is obtained through calculation, so that the horizontal displacement of the foundation pit support pile is obtained.The foundation pit support pile horizontal displacement measurement method has the beneficial effects that by means of the foundation pit support pile horizontal displacement measurement method, the four strain gages are only needed to be arranged on each measurement face of the metal rod in an attached manner; the strain of a corresponding position is calculated according to the strain capacity generated by the corresponding strain gages when the metal rod is bent; and the deflection generated when the metal rod is bent is calculated through the strain, and thus, the horizontal displacement generated by the inclined foundation pit support pile is reflected.
本发明提供了一种基坑支护桩水平位移的测量方法及装置，包括：沿着金属杆的长度方向，每隔一个长度单位标记一个测面；每个所述测面都环绕贴设四个应变片，所述四个应变片呈均匀间隔分布；将所述金属杆埋置于基坑支护桩内，所述金属杆的顶端露出于所述基坑支护桩的上表面；监测所述金属杆的顶端水平位移与转角，收集每个应变片的应变；经过推算得到所述金属杆上的每个测面的水平位移；从而得到所述基坑支护桩的水平位移。本发明的优点在于：本发明只需要在金属杆的每个测面贴设四个应变片，根据金属杆弯曲时应变片生成的应变量，计算出对应位置的应力，利用应力推算金属杆弯曲时的挠度，从而反映出倾斜的基坑支护桩产生的水平位移。
