| چکیده | ||
| Large deformation causing damage due to uplift force is generated in buried pipeline located in shallow trenches in marshes and saturated soils. 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. | ||
