测点周围环境变化对重力观测影响研究

The study of influence of the environment changes around the gravity sites in gravity observation

分析重力测点周围土壤浸湿和环境变化对重力观测影响的模型,计算了重力测点周围由于土壤浸湿和环境变化对重力观测的影响实例,结果表明:两种情况一般都会对重力观测造成一定影响,提出了在进行重力观测和重力资料分析时如何避免环境变化引起的重力观测影响的建议。

The models and examples of soil moisture and environment changes around the gravity sites in gravity observations are analyzed and calculated.The results show that the two cases above can all bring effect in about 20×10^(-8)ms^(-2) to gravity observations.How to avoid the effects in gravity observations and gravity data processing have been suggested.
