Abstract

Recently, ground subsidence frequently occurs in urban area. Ground subsidence results from many reason, among them, sewer leakage is one of the main reasons. Sewer leakage generates an underground cavity and this cavity develops ground subsidence. In this study, artificial underground cavity due to sewer leakage of decrepit sewer pipe is reproduced, using ice, in field. Ground subsidence was occurred after developing cavity and the resulting surface settlements were measured. In addition, numerical analysis was conducted to estimate developing settlements with size of the underground cavity.
