摘要
传统研究地表沉陷规律的方法是在地面设立观测站,然后通过其观测数据来推知。由于观测点数目有限而且观测点布距相等,使该方法存在诸多缺陷。本文提出了新方法,将FLAC软件应用于观测站设计中,实现根据地表变形特点对观测站进行优化布置,然后对数据采用数值微分方法处理,从而得到地表沉陷规律。算例表明,该方法简便,而且精度高,是一种合理有效的方法。
The conventional method, which research rules of surface sedimentation, is that surface observation station is set up, and the rules are estimated according to the data observed. The method has some defects because the number of observing points is limited and the interval of observing points is constant. The paper brought forward optimization design of observation station according to the characteristic of surface deformation when FLAC software was applied to design. The observed data of surface deformation were processed by numerical differential, accordingly, the rules of surface sedimentation can be educed. The example of calculation indicated that the method was precise, reasonable, simple and convenient.
