This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are considered. Herein, the ULS failure refers to the basal heave failure, while the SLS failure refers to failures sue to excessive ground-surface...

DOLERITE I T M S R E D S A N D involve the excavation of roots. While they are I l D unrivalled as a means of disclosing the spatial distriI . . ? bution of roots, they present only a static picture of 4 $2 a root system at one instant of time, so in order to study both the distribution of roots at different stages of crop growth and to compensate for soil heterogeneity, which may markedly affe...

Archaeological excavations in Romuald's Cave (Lim Channel, Istria, Croatia) have yielded evidence of human activity stretching back to the Middle Palaeolithic. This paper reports on recent Bronze Age/Early Iron Age discoveries uncovered during excavations as part of the Croatian National Science Foundation funded project: "Archaeological Investigations into the Late Pleistocene and Early Holoce...

The area of the tunnel face after blasting is a very important factor in underground excavations where drilling and method used. face, this significant that has affected cost safety constructions case using excavations. Because depends on many different parameters, such as geological conditions located, parameters explosion, other tunnel, it difficult to accurately determine value blasting. Thi...
