Reliability and Assessment Techniques on Ground Excavation


  • Sanga Tangchawal Chulalongkorn University



Ground excavation, reliability techniques, stability planning, blast impacts, optimized charge weight.


Planning and assessment on the excavation of the brittle materials (soil or rock) can be done by using the machinery and/or explosives. The reliability assessment has been proposed to predict the failure of ground during excavation process. The stability planning on cutting soil (rock) face by machinery can be compared between the deterministic and the statistical method. The risk of using explosives for rock excavation has to concern on the damage and environmental impacts after blasting events.
