Rehab or Replace? Foundation Testing Provides the Answer

Serial Information: Civil Engineering—ASCE, 1981, Vol. 51, Issue 6, Pg. 71-72


Document Type: Feature article

Abstract:

A $15 million, multidisciplinary testing program was undertaken to determine the least expensive methods of rehabilitating Locks and Dam No. 26 on the Mississippi River. The Problems were twofold�physical deterioration and inadequate capacity for handling increased barge traffic. Researchers investigated the feasibility of improving foundation soil characteristics and constructing additional support structures. The results confirmed previous studies�the whole project needed to be replaced at a new site. Among the tests described are a pile driving effects test, drilled-in pile tests, and rock anchor tests.
