Sinkhole collapse is one of the major hazards for people and property in the Middle East and North Africa (MENA) region, especially if the bedrock structure is karstic, covered by unconsolidated material. Our study identifies localized deformation …

This paper presents a numerical model for the evaluation of the active and passive seismic earth pressure coefficients against the retaining structures subjected to pseudo-dynamic loading using the lower bound limit analysis coupled with finite …

Laboratory critical state line (CSL) testing used in engineering practice to analyse the stability and liquefaction susceptibility of tailings explicitly assumes a unique CSL for a particular tailings. However, there is evidence of non-unique CSLs …

The dynamic properties of soil obtained from the torsional simple shear test (TOSS) are assumed to be uniform throughout the specimen. For some exceptional soils, this may hold true, but for the most majority of soils that we examine, it is …

The deformation and instability disasters of mining slopes in the Southwest China mountainous area are frequent. Moreover, geological disasters are characterized by large-scale, strong destructiveness and complex failure modes. To research the …

As a result of the developing industry and growing population a significant increase has happened in the volume of waste plastic bottles, consequently, their disposal has become a major concern. One possible recycling method is to use them in soil …

A proposed new type of retaining structure, multi-step cantilever retaining walls, has a wide application prospect because of light weight, quick installation, and good applicability for high fill earthworks. In light of the potential log-spiral …

In the present paper, the problem of finding the location of the so-called “characteristic point” of flexible footings is revisited. As known, the settlement at the characteristic point is equal to the uniform settlement of the respective rigid …

Rapid development in residential areas has increased substructure construction, which has become problematic in large cities. Deep excavation induces ground deformations such as lateral movement and vertical settlement in the soil mass adjacent to …

Accidents such as roof caving, water permeation, and instability of supporting structures often occur in the roadway in the fault fracture zone of the Beizhan iron mine after excavation because of the coupling effects of high ground stress …

This paper aims at to establish a novel approach of gravity blind backfilling method for abandoned mine voids using suitable backfill materials. Gravity blind backfilling is an important aspect for controlled movement of the overlying strata and …

This paper presents an innovative top-down construction method using a sequential peripheral wall (SPW) approach. The top-down method is a safe approach to deep excavation in an urban area. The conventional top-down approach begins with …

The development of materials formulated for similar simulation testing of small-scale models is the foundation of this work in order to carry out the physical model test investigation of the instability mechanism of the retrieved roadway beneath …

In cold areas, freeze–thaw cycles are important in the design of engineering projects since they affect mechanical properties of fine-grained soils. In freeze–thaw cycles (FTCs), soil engineering properties change as water transforms into ice …

A two-dimensional plane-strain finite element analysis based study is conducted to investigate the overall response of skirted strip footing resting on layered soil media comprising a loose sand layer overlaying a dense sandy stratum. The …

To study the strength deterioration and fracture mechanism of rock under the microwave irradiation, the experiments on the wave velocity and Brazilian splitting tensile strength of sandstones after different microwave irradiation time were carried …

Historically, deep foundations in weak rock have been designed as friction elements using frictional resistance (fs), calculated from the unconfined compressive strength (UCS) of rock. Most of the published correlations of fs to UCS were developed …

Rock-support interaction is the basis and premise of support structure design in tunnel engineering. In the conventional convergence-confinement method, the imperfect rock-lining interface is usually ignored. In this study, we present a mechanical …

Based on the upper bound theorem of limit analysis and variational principle, the uplift resistance of shallow horizontal anchor plates in heterogeneous soil and three-dimensional failure surface of overlying soil are investigated. The results …
