Post-Grouting을 이용한 하중분산형 앵커공법의 적용성에 대한 고찰

When excavation construction, ground anchorage that is the method of reinforcing temporary retaining well has the mechanism that conveys tension affected strand to grout and adhesion of strand. Friction type anchor mainly was used and simple tension type anchor and compression type anchor that can remove strand have been developed. After that time, it can be the history of evolution that compression dispersion type removal anchor that can expect the additional effect of load distribution was developed. In the study, construction site bulb confirmation test was conducted to figure out the effect of grout bulb formation on the soft ground. As a result of the test, capacities of other anchoring and Post-grouting anchor were compared. This study"s purpose is to provide basic data for applying for design by confirming load distribution and behavior by comparing and analyzing capacity of load distributive type anchor applied existing tension type anchor and Post-grouting.
