Algorithm for Selection of Geo-technical Technologies for Strengthening of Weak Bases

One of the main directions of geotechnical construction is the reconstruction of objects. This type of construction in most cases is associated with the need to strengthen the foundation bases. In this case, the principle of «technical feasibility and economic efficiency» when choosing the type of geotechnical technology should be observed. The article presents several geotechnical technologies to strengthen the bases. The principle of selection of technically expedient and economically effective type is considered. It is shown that the use of concrete piles (earth-cement pile reinforced with ERT pile) is possible to strengthen the foundations. In this case, its cost is cheaper the bored-injection pile without compaction of borehole walls. The algorithm of selection of technically sound and economically feasible type of geotechnical technologies when increasing loads on foundations which includes the determination of the number of strengthening piles under the bearing structure, the cost of the execution of bored piles, terms of production of the unit of the buried structure; actual bearing capacity, number of bored piles per foundation unit, is given.
