In this paper, existing common methods of pipeline anchorage are discussed and considering advantages and disadvantages of these methods, a new method of pipeline anchorage are studied and presented. In this new developed method, geo-textile materials are used for anchorage of large diameter pipeline. Laboratory and field experimental study are developed and effective parameters are deliberated considering load–displacement curves. Finally, a field study on a 30" diameter gas pipe is performed to admit the laboratory tests. Considering the laboratory and field study results, the anchorage of pipeline using geo-textile is recommended for anchorage of buried pipeline in marshes and saturated soils.
