| Abstract: | Combining Xiaozhai grand bridge from Zhengning to Shenjinguan expressway,it synthesized some methods to prospect,such as engineering geological drilling、trenching、tunnel、situ-testing and surface engineering geological mapping,and find out the hydrogeology and engineering geology condition in detail,evaluated the rationality、site stability and harmful geologic body of bridge location.Then,the construction scheme,＂side slope managing first foundation excavation later＂ has been suggested and ensured the safety and time. |
