چکیده
Abstract A comparative analysis of the solutions for seismic impact on a flexible retaining wall designed to strengthen construction excavation multi-storey building in Sofia has been performed. For this purpose, following FEM calculation models interaction with surrounding soil body were compiled: (1) 1D beam-column-spring model wall, including spring support its embedded length and pseudostatic loading active earth pressure, determined by Mononobe-Okabe method; (2) 2D body, form inertial forces applied at finite element nodes; (3) time history FE conducted accelerograms two landmark earthquakes from Balkan Peninsula - 1976 Vrancea (Romania) earthquake 1986 Kalamata (Greece) earthquake. The analyzes was basis reference acceleration 2.3 m/s 2 , city according hazard map Bulgaria. scaled maximum value PGA = . physical modelling uses HSM HSsmall advanced constitutive laws, implemented Plaxis software.

متن کاملThe deformation of retaining piles and ground surface under various support systems during deep excavation
Background: Since the high-rise buildings and deep underground structures dramatically increases in urban area, the decent design and construction of deep excavations is essential before these structures are actually built up. The building area is very susceptible to the changes of their geo-environment, and even minor insecurity of a deep excavation may lead to a catastrophic failure of struct...

متن کاملapplication of long-short pile retaining system in braced excavation
in soft soil areas, equal-length piles are often adopted in the retaining system. a decrease in the bending moment value borne by the retaining structure along the pile depth (below the excavation bottom), leads to an inadequate use of the pile bending capacity near the pile bottom. this paper presents retaining systems with long and short pile combinations, in which the long piles ensure integ...

Optimal design of cantilever reinforced concrete retaining wall can lead considerable cost saving if its involvement in hill road formation and railway line formation is significant. A study of weight reduction optimization of reinforced cantilever retaining wall subjected to a sloped backfill using Differential Evolution Algorithm (DEA) is carried out in the present research. The r...
