Application Study On Consolidation Of Soft Soil Area Of Deep Foundation Pitanchor Electrochemical

In deep excavation engineering in soft soil area, because the soft soil has low shear strength and the rheological characteristics of strong, high void ratio, and water. Traditional grouting anchor cable anchorage is hardly to put the design requirements. According to such practical engineering problem, a deep foundation pit engineering in yingkou district, this paper electrochemical reinforcement through the field test of anchor cable in the research and application, and obtained the certain effect.Electrochemical reinforcement method for reinforcement method with other traditional reinforced the construction period is short, site construction convenient, low cost advantages. Therefore, the reinforcement method of deep excavation engineering in soft soil area of anchor cable reinforcement has a certain significance.Electrochemical consolidation method is a involves multi-disciplinary, multi-field strengthening methods. Electrochemical reinforcement including electroosmosis, electrophoresis, physical-chemical reaction, heat effect, soil structure change and a series of physical and chemical reaction process, in the electrochemical reaction, the role of electricity let to the anode is close-grained, surrounding soils and iron hydroxide colloid on the soil of the anode corrosion cementation. When will anchor cable as the anode, the anchoring force will be greatly improved.In this paper, the anchor rope do some in-depth study of electrochemical method. The main work and research content is as follows:1, this paper summarizes the main characteristics of deep excavation engineering in soft soil area, aiming at the lack of anchor cable anchorage force, first proposed the anchor cable of electrochemical consolidation method, and the engineering practice, good results have been achieved.2, summarizes the development of electrochemical consolidation method, the detailed mechanism and strengthening the role of electrochemical micro process, summarized the electrochemical characteristics of the reinforcement method and the applicable scope;3, through the test set, a soft clay engineering in yingkou city, liaoning province as test object, indoor cable electrochemical reinforcement and grouting reinforcement and electrochemical test such as grouting reinforcement; Comparative analysis of different forms of anchor cable reinforcement ultimate anti-pulling capacity, and gives three kinds of reinforcement in the form of ultimate pull-out capacity curve and creep test curve.
