ANALYZING THE INFLUENCE OF THE EXPLOSION DEPTH ON THE STRESS-STRAIN BEHAVIOR OF CIRCULAR TUNNEL IN SATURATED SOIL

Abstract

This paper presents the effects of the explosion depth on the stress-strain behavior of circular tunnel in saturated soil with 2 approaches: experiment and numberical method (SAP2000 ver 12.0). The result of experiment and numerical methods indicate the factors on the declining of explosion energy for design the tunnel in saturated soil subjected to blast loading purpose.
