Abstract

Newdesign loads onMerano-Malles Railways Line required structural and ground improvement along the whole line and particularly on a couple of XIX century masonry arch bridges near Silandro village, N-E Italy, South Tyrol region. The need tominimize downward-settlements during ground improvement operation, alongwith the target to create a controlled upward liftup of treated footings, brought our design choice toward an extremely delicate and totally monitored Multistage-Multiport Low Pressure Grouting solution, based on Manchettes - pipe technique. A Successful Design concept, Grouting details, Monitoring results are presented in this paper.
