Highway embankments stability during its service period represents an important factor for the safety of highway users and vehicles. Consequently, the cost of construction of these embankments should be adequate to maintain the safety and durability during this period through proper estimation of the loading on asphalt pavement, slope stability, horizontal and vertical deformation, etc. Slope stability of the embankment mainly depends on the shear strength of the soil layers materials; this shear strength is affected by the water table level through the contribution of the capillary water.

Soil slope is one of the main parts of the road engineering. The stability of the slope is an essential prerequisite to ensure the safe operation of road transport. In seasonal frozen regions, shallow landslide hazards in soil slopes usually happen, which pose a serious threat to road safety operations. During the melting process, there forms stagnant water lubrication between the melting soil and freezing soil interface, which constitutes the weak interface of landslide hazard. Special methods to form the freezing — thawing F-T surface is designed, and takes consider the interface strength as the foundation of experimental tests, then opening to research the soil slope stability. Safety factor modification of the soil slope is presented. The conclusions of this paper present well theoretical and applied value to the regional slope failure analysis.

UTexas4 is a computer software application for computing the stability of earth and earth-rock slopes and embankments. Stephen G. Wright of Shinoak Software, who is well-recognized as one of the leading experts in solving problems in soil strength and slope stability Duncan and Wright, UTexas4 has been considered one of the most sophisticated commercial software available to study the stability of slopes using a two-dimensional, limit-equilibrium method. UTexas4 features unique random techniques for generation of potential failure surfaces for subsequent determination of the most critical surfaces and their corresponding factors of safety.

Research on the Soil Slope Stability Based on Soil Strength Deterioration in Seasonal Frozen Areas

Diederichs, M. This paper is intended to illustrate the applicability of Shear Strength Reduction SSR as a general technique for obtaining Factor of Safety estimates for slopes in variable geology, progressive or locally brittle yield behaviour and with ground-structure interaction. Implications of the assumptions required to ensure this correlation are discussed including uniform stiffness, rigid-plastic behaviour, instantaneous interaction between geological units, and instantaneous generation of support loads. General applicability of the method is demonstrated and the limitations explored using Discrete Element simulation of multi-block slope failure. The methodology is general and can be applied to other non-linear problems such as multiblock discrete element simulations. Geotechnical engineers primarily conduct slope design based on calculated factor of safety values. Limit Equilibrium LEM techniques that compare resisting forces to driving forces or moments are ideally suited to the generation of a nominal safety factor Krahn

Much has been learned about the shear strength of soils within the past 60 years, often from surprising and unpleasant experience with the stability of slopes, and.

Он протягивал свою изуродованную руку… пытаясь что-то сообщить. Танкадо хотел спасти наш банк данных, - говорила она.  - А мы так и не узнаем, как это сделать. - Захватчики у ворот.

Похоже, в них угадывался страх. Или это ненависть. Они буквально пожирали ее тело. Новая волна паники охватила Сьюзан. Хейл всей тяжестью своего тела придавил ее ноги, холодно следя за каждым ее движением.

При этом внезапное отключение электроснабжения не прерывало работу ТРАНСТЕКСТА и его фреоновой системы охлаждения. Если бы этого не было, температура от трех миллионов работающих процессоров поднялась бы до недопустимого уровня - скорее всего силиконовые чипы воспламенились бы и расплавились. Поэтому такая перспектива даже не обсуждалась. Сьюзан старалась сохранять самообладание.

 Извините, что я вас побеспокоил, но скажите: вы, случайно, не были сегодня на площади Испании. Глаза старика сузились. - Вы из муниципалитета.
