Regularities of development of settling of models of deep footings

Conclusions 1. The effect of relative penetration on the change in magnitude of settlement is substantial. With the same specific pressure on the base the settlement of the model decreases as the relative penetration increases.2. Published data on values of unit friction forces along lateral surfaces of deep foundations were confirmed. The maximum value of resistance along the side surface was 2 tons/m².3. It was established that the realtionship between the settlement of the model and its diameter is nonlinear. This is of great importance in working out a method for calculating foundations of deep footings from deformations especially if one considers that in this case the foundation carries substantial pressures and deforms under conditions of strongly developed shear regions.Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 6, pp. 11–12, November–December, 1971.

巷道围岩塑性区的德鲁克-普拉格准则解

考虑到巷道围岩屈服与中间主应力有关,运用德鲁克-普拉格准则推出了圆形巷道塑性区半径及应力的解析解。结果表明,在考虑中间主应力的情况下巷道围岩塑性区增大,证明中间主应力对塑性区具有一定影响。因此,该理论成果弥补了以往理论未考虑中间主应力的不足,也为巷道围岩塑性区的理论分析提供了一种新的理论计算方法。

Investigation of causes of emergencies of buildings in the city of Nukus

Drying-up of the Aral Sea and increase in the mineralization level of the Amudar'ya River affect the construction conditions in the Aral Southern Region. It is shown that the causes of building failures in the city of Nukus are rise of the groundwater level and increase in the water mineralization. Specific recommendations are given for protection of the buildings against aggressive groundwater action. Karakalpak Branch of the Academy of Sciences of Russia.

Studies of the rate of migration of radiocesium in some types of soils of Eastern Poland

The activity of Cs-137 and Cs-134 in some types of soils of Eastern Poland was studied. The contribution of Cs-137 from post-Chernobyl fall-out as a function of depth in the soil profiles was calculated from the Cs-134:Cs-137 activity ratio taken from the literature just after the Chernobyl accident. Such information makes it possible to calculate the rate of vertical migration of radiocesium in various types of soils. The rate of the post-Chernobyl Cs-137 migration was found to exceed the rate of migration of Cs-137 from experimental nuclear explosions in the atmosphere. Cs-137 from the Chernobyl accident was found in a layer of soil a few cms thick in most of the soils which were examined. The contribution of post-Chernobyl radiocesium to the total contamination of the surface layer (0–5 cm) with cesium was ≈77%.

对湿陷系数、本构模型和弦线模量等几种计算湿陷变形的方法进行了评价.对比原位浸水和载荷试验结果,湿陷系数计算湿陷变形误差很大,本构模型尚未在工程中推广应用,弦线模量计算湿陷变形最为准确.由于能够准确计算湿陷变形,因而能够按变形控制进行湿陷性黄土地基的设计.     

Prediction of accumulation of seismic deformations of bases

A calculated and experimental method was developed for predicting irreversible settlements of foundations during the operation of a structure, taking into account the shakability of the construction site. This article suggests a way of processing seismological information about recurrence not only of the maximum earthquake for which the structure is designed, but also more likely actions of a lesser level. A procedure is set forth for vibrodynamic soil tests to obtain the original matrix of experimental data about formation of residual deformations within the bounds of compressed strata of the base as a result of application of dynamic actions on different combinations of a static state of stress. These data are used to calculate seismic settlements of the foundation, taking into account the probability of seismic events of different levels during the standard time of the object's operation.Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 6, pp. 15–18, November–December, 1992.     

桩体刚度对复合地基支承路堤失稳破坏模式的影响研究

在已有研究基础上,对理想塑性、脆性拉裂两种破坏后性状对应桩体的抗弯、抗剪承载力的进行了分析比较,脆性拉裂破坏后性状可以更好地反映桩体弯曲破坏后抗弯及抗剪承载力的降低。对于复合地基支承路堤的有限差分数值模拟表明,路堤荷载、桩体材料弹性模量不同时桩体受力以及路堤失稳时桩体的破坏模式并不相同,当桩体弹性模量、路堤荷载较大时,桩体发生受拉弯曲破坏,需考虑桩体的脆性拉裂破坏后性状以描述桩体抗弯、抗剪承载力的降低以及不同位置桩的连续破坏。

Modelling of probability of failure of concrete columns

This paper predicts the probability of failure or short and long columns of square reinforced concrete for deterministic and probabilistic loads. The effect of various parameters; width, length of column, effective length coefficient, percentage of steel, axial load, grade of concrete and random numbers; on the probability of failure of the column is studied. The material, geometric parameters and the load are treated as probabilistic. The results for short columns show that the rate of decrease of probability of failure is a maximum with increase in width, while it increased to a maximum with increase in loads, whereas for long columns the length of column had the predominant effect.
