摘要

初步采用高斯函数来模拟隧道开挖引起的地表沉降,但高斯函数不能描述孔隙率对地表沉降的影响。为解决这一问题,应用Yu分形理论对多孔体的几何特性进行了建模,并采用分形孤立波对表面沉降曲线进行了建模,讨论了最大表面沉降、孔隙度和Yu分形维数对沉降曲线的影响。该模型为地表沉降形态的预测提供了新的思路。

A fractal model for the tunneling-induced ground surface settlement
The Gaussian function was initially adopted to model the tunneling-induced ground surface settlement, but it could not describe the porosity’s effect on the settlement. To solve the problem, Yu’s fractal theory is implemented to model the porous grand’s geometric property, and the surface settlement profile is modeled by a fractal solitary wave, furthermore, the effects of the maximal surface settlement, the porosity and Yu’s fractal dimension on the settlement’s profile are discussed. The new model offers a new view to predict the morphology of the surface settlement.
