Preliminary investigation on use of PE geotextile in damp-proofing of cave storage having bolt lock struc-ture with shortcrete;

This paper introduced the basic paint design principal for metal oil tanks and prepared paint systems for different parts of cavern metal oil tanks under corrosion environment.

The anticorrosion construction experience for metal oilcans in cavern were summarized and the implementing regulations in welding technology,anticorrosion construction technology,strengthening anticorrosion in tank bottom floor,and paint anticorrosion were introduced.

And as an engineering measure, a concept of “tidal basin” is developed to accommodate tide and to move sediment.
