摘要:
通过环境调查等手段,收集整理马家岭水准观测场地周边环境变化参数及岩土力学参数,运用不规则二维载荷模型计算荷载引起的水准高差变化。结果显示,霍山大峡谷漂流场地停车场的建设对马家岭水准观测有一定影响,影响量约为0.77mm,与实际观测高差0.70mm接近,研究结果从定量模拟的角度证实了马家岭流动水准异常为环境荷载变化引起的地面高差变化。

Abstract:
This paper collected parameters of environment changes and rock mechanics by environmental investigation at the observation field of mobile level at Majialing,and calculated leveling height difference by load changes around an irregular load model. The results showed that the construction of the parking lot of Huoshan grand canyon rafting has some influence on the Majialing level observation. The influence effect is about 0.77mm,and close to 0.70mm difference from the observed height. The result shows from the point of view of quantitative simulation that the Majialing mobile level anomalies are caused by the surface load changes.
Key words:  Mobile level  Environmental disturbance  Load model  Quantitative simulation
