Discussion on Calculation of Front Resistance in Landslide Anti-slide Pile Design
When engineers and technicians design anti-slide pile in landslide control project,they should consider the problem of inconsistent of front resistance of pile.Taking a landslide in Kaizhou District of Chongqing as an example,the conditions of considering the pile front resistance,the calculation method,and the influence on the force of the anti-slide pile under different stable states are studied.Comparative analysis shows that the pile front resistance should be considered when the sliding body in front of the pile is stable(i.e.stability coefficient Fs≥ safety coefficient Fst).According to the minimum stability factor equal to the safety factor,the resistance of sliding body in front of pile is more conformed to the design principle of"taking proper consideration of the resistance in front of pile".The design of anti-slide pile is economical and has a certain safety reserve.
