Essay

The paper is devoted to elaboration of effective constructions of pile anchors with widenings along shaft length for fixation of petroleum and gas pipelines from emerging on saturated plots, complex experimental-theoretical research of stress-strain state of their bases and perfection of their calculation technique. New constructions of pile anchors with widenings along shaft length have been confirmed, on the conception of application of bigger soil volume with increased physical and mechanical characteristics and sizes compaction zones over widenings that provide the increase of bearing capacity of anchors on pull-out loads. In natural conditions their interaction with sandy and clayey bases including parameters of soil compaction zones around the shaft and anchors widenings have been researched. The determination technique of base stress-strain state of such anchors during their erection and maintenance by method of ultimate elements in physically and geometrically non-linear presentation with theuse of soil strain elastoplastic model has been elaborated. Formation peculiarities of soil displacement and compaction zones during erection of pile anchors and spaces of soil ultimate limit state around them under pull-out loads. The new engineering calculation of bearing capacity of pile anchors with widening at the shaft length, that accounts the form of "press-out body", the method of anchor erection, type of soil and its strength characteristics have been elaborated. The use of pile anchors for stabilization of gas pipelines instead of loads permitted to reduce the amount of erection elements 1,5-3,4 times, reinforced concrete - 2-4 times.
