Prefabricated Vertical Drains. Volume 3. Laboratory Data Report

摘要

The objective of the discharge capacity testing summarized in the volume was to fabricate a testing device and perform vertical discharge capacity tests on selected prefabricated vertical drains (PV). The results of the tests were evaluated to determine the feasibility of the method as a standard. Based on the literature review and technical interviews, an apparatus was designed and fabricated for the testing of PV drain discharge capacity. The device is described in detail in the volume. The device was used to test five PV drain products with varying confining pressure and applied gradients. Typical test results are include along with all the laboratory data.
