Abstract

Groundwater leakage in shield tunneling causes deterioration of not only the tunnel but also the surrounding earth formation. Therefore, groundwater leakage is an important question when tunnels are considered in view of their durability though the leakage maintenance requires an investment of money. Because the water leakage occurs at segment joints in most cases, a selection of segment sealing materials plays an important part in tunnel waterproofing. So far, the selection of the seals, forms and measurements has been determined by experience and actual results. Thus, design for the waterproofing is yet to be standardized. In this report, various waterproofing tests using hydrotite seals which are most widely used are presented. Based on the test results, a proposal of the waterproofing design based on packing principles is also presented in this report.
