摘　　要：从理想流体的欧拉动力学方程出发,通过建立水管倾斜仪一端钵体受施工干扰的理论模型,计算钵体中液面因施工带来的高差变化,并与实际观测资料进行比较。结果表明:施工干扰的力源是直接通过基岩传递到水管倾斜仪基座与位移传感器上而非通过钵体中液体;施工振动干扰只表现在幅度上。Starting from the euler dynamic equation of ideal fluid, the paper calculates water surface altitude difference change in the pot body due to construction through establishing theory model of water tube tilt meter that one end of the pot body is disturbed by construction, and compares with the actual observed data. The results showed that： the force source of construction disturbance passed on the water tube tilt meter base and displacement sensors through the bedrock directly, rather than through the liquid in the pot body; construction vibration interference displays only on the amplitude.
