In order to reliably grasp the complex topographic and geological conditions,this paper takes the rapid upgrading engineering of Zhuhai Avenue(west section of Jinwan Interchange)as an example.The physical and mechanical parameters of soil layer,foundation bearing capacity and deformation modulus are measured by PS wave velocity test method and cone dynamic penetration survey technology respectively.According to the measurement results,it provides a reliable basis for construction,aiming to ensure the construction quality to the greatest extent.
