Influence Research on Pit Excavation Close to Existing

Pit excavation has a negative impact on the existing shield tunnel close to it. The deformation mechanism of the existing tunnel during the pit excavation was analyzed. Theoretical analysis results shows: excavation unloading decreases the pressure in horizontal direction of the tunnel, which causes tunnel taking the horizontal displacement to the pit side; convergent deformation …

Simplified analysis method for predicting the influence of

deep excavations. For establishing the factors that influence the performance of deep excavations, we have created a geotechnical model of an excavation. This was done by statistical analysis of a database for retaining walls and ground movements due to deep excavations. Before statistically analyzing the database

Research on the Influence of Excavation and Loading on Z

To probe into the pattern in which the excavation and loading process have on such factors as stress and displacement in neighboring regions of deep open pits, a mechanical unloading model in coal mining process and another model for the loading process are set up respectively. Besides, FLAC 3D software is used to simulate dynamic excavating and loading process in …

Apr 18, 2018 · Abstract. In order to study the influence of subarea excavation on the deformation and stress behavior of a subway foundation pit, the deep horizontal wall displacement, supporting axial force and surface deformation were measured and compared with other similar pit cases according to the case of a soft soil deep foundation pit for a metro station in Hangzhou.

[PDF] Study Achievement of Deep Excavations from the Point

Starting from concrete situations encountered in the city of Iasi,Romania, are presented the methods used by the authors to assess the influence siting of new construction in urban areas, densely built. The results are compared with measurements made to support deep excavation and settlements for new buildings and those are in the "zone of influence" them.

Research on the Influence of Deep Foundation Pit

Up to10%cash back · Jan 28, 2021 · According to the research conclusions (Yu and Xiao 1987; He et al. 2008 ), the excavation of the chamber is an irreversible process, and the mechanical response of the surrounding rock stress is related to the loading path. At the same time, the mutual influences of the excavations in time and space should be avoided.

Investigation of the influence of soil-structure interface

Nov 23, 2015 · In deep excavations, there are large areas of interface between the soil and structures (e.g. the retaining wall, and piles). The interface properties may affect the performance of deep excavations. In finite element analysis of deep excavations, tie constraints are commonly assumed at the soil-structure interface for simplicity, but this

Field investigation of the influence of basement

Nov 01, 2021 · Fig. 2 shows elevation views of the basement at sections A-A and B-B. The final excavation depths in sections A-A and B-B were 14.5 and 17.0 m, respectively. To reduce basement excavation effects on nearby buildings, bore piles with a diameter of 1.0 m and a spacing of 0.8 m were constructed as retaining walls.
