ความเสี่ยงเชิงเสถียรภาพของการขุดเจาะเปิดหน้างานดินและหิน

Abstract

Analyses on stability of face excavation in soil (or rock) materials can concurrently process using both the deterministic and the reliability methods. The proposed probabilistic method in this article, field data are assumed to have either normal or lognormal distribution. Application of reliability method can lead to the value of probability of failure, in which it can compare with the factor of safety obtained by the deterministic method. Using of both methods, the risk from face excavation can be reduced, environmental impacts be better protected, and the cost of excavation be further optimized.
