| Abstract: | Fenghuang-Daxing highway k0+500~k5+000 passes through the Phoenix National Geology Park in the Qiliang Cave scenic area.To analyze the influence degree of highway construction on geological heritage and forecast the effect of blasting vibration and vehicles load function,this paper makes use of the PLAXIS software to simulate and analyze the biggest influence degree on geological heritage.It computes the total blasting explosive charge precisely and draws the conclusion that the highway construction(blasting vibration & vehicles load) cannot have the adverse effect on the Qiliang under the condition that the highway is constructed normally according to the standard. |
