Abstract

In view of the risk of ground settlement induced by construction dewatering of Taizhou Bridge anchorage caisson foundation, the thesis tries to determine relative weights of various settlement-inducing factors on assessment objectives by employing an analytic hierarchical process. Another the multi-level comprehensive assessment is then applied by a comprehensive fuzzy evaluation method, so as to establish a scientific risk assessment system of ground settlement induced by construction dewatering of Taizhou Bridge anchorage caisson foundation..
