COMPACTIONThe possibility for the calculation of the soil bulk density from two-dimensional penetration resistance diagrams drawn using a penetrometer during the vertical sounding of the soil has been discussed. A method has been proposed for calculating the bulk density of loamy sandy soddy-podzolic ...

摘要: This paper respectively uses the method of expansion of cavity and FEM to analysis the soil compaction effect of anchor jacked pile while sinking,and compares the calculation result of the two methods by combining effect is valuable to the application of engineering.关键词:...
Early planting dates, large amounts of crop residues on the soil surface, and soil compaction may subject plants to more stress. Banded nutrients are usually more effective for crops under these stress conditions. Vegetables respond well to banded fertilizers because they require a relatively large ...
The proposed method, in an original way, explicitly takes into account the geometry of the geocell pocket, effects of soil and geocell-reinforcement stiffness, compaction-induced stresses, soil strength and strain compatibility. The method can be used both analytically and using simple and presented ...
Therefore, our aim was to develop a general approach to calculate the effect of SOM concentration on ρb that would be universally valid for soils different in their genesis, compaction, and type of land use. To describe the effect of SOM on ρb mathematically, we used a nonlinear ...
of the speed of the elastic waves and density of objective soil quality, to operate the density of the banking and a degree of compaction is judged by the comparative operation of the operated density with the maximum dry density of the objective soil quality and the compacting execution of ...
The following are determined as the result of calculating the explosion: volume of the explosion crater; mass of soil ejected; mass of soil left in the compaction zone; radius of the compaction zone; volume of soil in the heap and its profile. The indicated effects, with the exception of ...
It is known that screw piles not only do not violate the soil during immersion, but, as shown by numerous tests, soil compaction occurs. The design of a pile-screw anchor of increased horizontal susceptibility is presented, which allows to increase the carrying capacity of a conventional screw...
In most cases, in design, the theory of a homogeneous isotropic linearly deformable medium is used to determine the deformations of soil foundations. In the article, the authors propose to use the one-dimensional problem of the theory of compression soil compaction to calculate the settlement of ...
