Analysis and study on failure type and mechanism of soldier pile
Soldier pile is an important supporting form of slope and deep excavations,with the large-scale development of construction,the use of soldier pile is becoming more and more.The slope failure accidents followed happen and the damage of soldier piles are part of them.However at present,the research on the failure of soldier pile is scarce at home and abroad.Based on the analysis of the failure phenomena of the soldier pile in the projects,combined with the generalized model of the failure force of the pile and numerical simulation,the failure type and mechanism of the soldier pile are studied.The study results show that according to the failure characteristics of the supporting pile,the failure of the soldier pile can be divided into three types,i.e.pushing inclined,shearing damage and bending failure.The types are governed by their geological conditions and the supporting system.Finally,based on the mechanism analysis,the countermeasures are put forward.The conclusions and suggestions of the paper can be referred by the slope engineering in the failure cause investigation,emergency rescue,stability assessment etc.it also could be referred in the slope investigation,design and construction works.
