retaining wall movement monitoring

  • observation was the cantilever movements at the top of the support walls. Survey prisms were mounted at three such locations along the west wall to provide real time performance data. A project web site allowed all interested parties access to the data. The paper illustrates how real time monitoring and careful design can ...


  • The results of the monitoring program indicated that the wall movements were limited to less than 3/4 of an inch during the 17 months monitoring period, and the walls appear to be in satisfactory working condition. The appearance of the criblock retaining walls as well as their durability can make this retaining wall system.


  • subsequently had to be removed and replaced (Jansson 2013). After this failure. MDOT started monitoring several sections of retaining wall along the highway that indicated movement. During the spring of 2014 it was found that several sections of wall had experienced significant movement near the location where Meyers ...


  • Subsequent monitoring of the wall revealed that lateral displacement of the wall continued to develop, and that additional stabilization measures were required. Design of the additional stabilization was performed in stages. Initially, a geotechnical investigation was performed to assess the potential causes for movement.
