Deep Pit

China University of Geosciences (Beijing) has developed a dynamic compaction and compaction grouting (DCCG) method for groundwater flow control in Dalian. This method has been proven effective in dramatically reducing permeability in plain fill soil, and in granular or porous media. It has been successful used in many applications dealing with deep pit by coast. This paper presents the DCCG that has particular relevance in today’s pit construction marketplace by coast. Permeability can be improved by means of the DCCG. A brief introduction to the technique is followed by discussion of recent advances, illustrated by case studies of applications

Trace Element Uptake

Field experiments evaluated yield response to deep-pit poultry manure application to barley on a clay soil near Prince George and a grass-legume forage on a silty clay loam soil near Chilliwack, B.C. Substantial dry matter yield increases were measured at manure applications up to 20 t ha−1. Subsamples of both crops and the poultry manure were analyzed for Cu, Zn, Mn, Ba, Pb, Ni, Cr, Cd, B and Co. Selenium analyses were made on selected crop samples. There were no indications of toxicity problems even at 40 t ha−1, the highest application. Copper and Zn concentrations in forages were increased by the poultry manure and the Mn/Cu ratio tended to decrease with manure application.

The article considers the methods for calculating the predicted maximum settlement of buildings in the zone of influence of a deep pit in the conditions of St. Petersburg. There have been analyzed the results of calculations of the predicted maximum settlement by the semi-empirical method developed by Professor N. S. Nikiforova with the settlement values obtained in Plaxis 2D software package. The authors present the evaluation of the possibility of applying a semi-empirical method for determining the predicted settlement of the surrounding building development in the engineering and geological conditions of St. Petersburg.

Abstract Presented paper is dedicated to problems of deformation of the Earth's crust as a response to the surface loading caused by continental waters. The aim of this study was to specify areas particularly vulnerable to studied deformation and to compare calculated and observed displacements. Information of the continental water volume was taken from the WaterGAP Global Hydrological Model. Calculated values of the deformations were verified with the results obtained with programs SPOTL and grat. Vertical deformations were almost 10 times higher than the deformation in the horizontal plane, for which reason later part of the paper focuses on the former. In order to check agreement of the calculated and observed deformation 23 stations of International GNSS Service (IGS) were selected and divided into three groups (inland, near the shoreline and islands). Before comparison outliers and discontinuities were removed from GNSS observations. Modelled and observed signals were centred. The analysed time series of the vertical displacements showed that only for the inland stations it is possible to effectively remove displacements caused by mass transfer in the hydrosphere. For stations located in the coastal regions or islands, it is necessary to consider additional movement effects resulting from indirect ocean tidal loading or atmosphere loading.

The Finite Element Model

Based on the appearance of crack of enclosure piles on a foundation pit, Midas GTS is adopted to establish the finite element model. Through the numerical simulation, the influence of the direction of wind load, wind scale and prestress of anchor are analyzed, the worst wind load direction, unfavorable construction condition, maximum moment of enclosure piles are ensured, crack width in different disadvantageous factors are calculated, which provides a guide for continuous construction.
