The scientific utility of Eugène Dubois’ Pithecanthropus erectus (P.e.) specimens and other paleontological finds from Trinil has been impaired for over a century by questions about provenience. Firsthand accounts and...

Las exploraciones de Roth, las colecciones resultantes muchas ahora ubicadas en La Plata, Zúrich, Ginebra y Copenhague, y sus importantes aportes en temas geológicos -especialmente estratigráficos- y paleontológicos,...

Advanced geological prediction is one essential part in tunnel construction, and 3D E-SCAN resistivity device is introduced. In this device, the current and measuring electrodes are arranged on the tunnel face, which can...

The settling column tests and the vacuum preloading model tests are performed on the waste slurry of a construction site in Shanghai and the additive agent slurry. The sediment and turbidity characteristics of slurries w...

Under the framework of bounding surface plasticity and critical state concept, by introducing the disturbed state concept for hardening variables of elastic behavior, structured yield surface, structured bonding adhesive...

There is a series of symmetric deep-seated cracks (DSC) in the abutment slope of Yebatan Hydropower Station. The special geological phenomenon is analyzed to provide a scientific basis for a comprehensive analysis on roc...

A small-scale physical modelling system is developed to study the pull-out mechanism of embedded soil nails based on transparent soil and particle image velocimetry (PIV). Four types of soil anchorages, common cylindrica...

In order to obtain the criteria and precursor characteristics of critical rock fracture, laboratory experiments on the characteristics of acoustic emission (AE) of gritstone specimens under uniaxial compression are carri...

In order to study disaster evolutionary process and failure characteristics of Yonglian tunnel of Ji'an-Lianhua highway under the effect of disturbance, taking F2 fault fracture zone as the research object, a large-scale...

obvious influence on the failure strain than on the initial yield strain. The non-uniform distribution of fine soil has a more significant influence on the initial yield strain than on the failure strain. Key words: fi...

Based on theoretical analysis, the spectral element method is used to study the effect of bedrock terrain on ground motion. The achievements are as follows: (1) The intensity of bedrock ground motion is related to bedroc...

Soil acidity is one of the reasons for corrosion of steel piles. The material deterioration of steel pile foundation served in the acidic soil will affect the safety and durability of pile foundation. In order to underst...

The property of the soil in free field is an important influencing factor for the free field seismic response. In the existing studies the soil at local site is supposed to be the single-phase medium or saturated porous ...

As the water pressure of shield tunnel increases, the key to tunnel construction is to strengthen the water resistance of joints. By analyzing the characteristics of stress and deformation of the gaskets in the joints of...

Using the ring shear apparatus, the variation rules of residual strength of 17 saturated claysoil samples with different plasticity indices under different consolidation conditions are studied. The influences of current ...

The large-strain self-weight consolidation theory is widely used for the design of dredged material disposal sites and the treatment of hydraulically dredged slurries in the disposal sites. The self-weight consolidation ...

Qwing to that the common cement paste used in the complex soil strata with wide steep seams and loose space cannot fill firmly and run along the gaps, a new type of SJP cement paste is developed, which has great initial ...

The in-situ measurement formula for rock permeability is derived based on the theory of steady gas seepage. A rough judgement method for Darcy seepage in engineering is given based on the Pavlovsky’s Reynolds number fo...

In order to study the influence of non-uniform distribution of fine soil on mechanical properties of coarse-grained soil under freeze-thaw cycles, triaxial shear tests are conducted on different specimens with different ...

The interaction of cracks with different locations and sizes is a key factor leading to the damage of rock. Based on the Kachanov method, the interaction rules between two offset parallel cracks with different level inte...

According to the landslide characteristics of the slope of the reservoir bank of Longjiang Hydropower Station in Yunnan Province, laboratory tests are conducted to investigate the characteristics of the landslide under t...

According to deformable coordination condition, the sliding soil mass will deform to adapt to the curve of logarithmic spiral which will lead to energy dissipation. To quantify this energy dissipation, two multi-blocks p...

Good air tightness of filter membranes is necessary for opening excavation chamber under high pressure. To improve the value of air tightness, one should understand the pore structure and permeability change of filter me...

The methods for loess collapsibility mainly include field immersion testing method and laboratory testing method. A majority of the results of laboratory testing method differ greatly from the engineering practice. The d...
