摘要

Containerization of Army cargo for use in overseas theater of operations is progressing. The discharging of containers from containerships and moving them across beaches in logistic over-the-shore operations is a problem that the Army must be capable of handling. The objective of this study was to investigate sand-grid confinement and membrane reinforcement concepts for possible application in moving containers over unstable beach sands using wheeled vehicles such as the XM 878 truck tractor and XM 872 semitrailer. In particular, it was desired to determine the optimum grid cell size and minimum surfacing requirements for handling the over-the-shore container operations. A secondary objective was to test the potential use of buried membrane as expedient means for enhancing truck-semtrailer trafficability over beach sands. Two test sections containing a total of 14 test items were constructed and subjected to truck traffic. The tests included three membrane reinforcement items, 10 sand-grid confinement items, and one control item. Also tested in conjunction with the test items were four expedient-type surfacings.
