This paper aims to propose an efficient slope reliability Received in revised form 20 April 2015 updating method based on the direct MCS. First, the direct MCS is briefly introduced. Thereafter, a Accepted 21 June 2015 weighted approach based on the direct MCS is proposed for slope reliability updating. Furthermore, Available online 17 July 2015 the implementation proce
