What are the Methods of Interpolation of Contours?
What will be the best method to calculate vertical stress of soil in geotechnical engineering ?
It depends on the condition of soil. Wt of dry soil +wt of water in soil + overlying Wt if any and so on. read the fallowing article in google for better idea. Vertical stress in the ground

See lessIs it possible to obtain some data on factors on which seepage in dams depends?
Absolutely Yes, factors of seepage are very important to determine before the construction of a dam or even after the construction of the dam for maintenance work.

Absolutely Yes, factors of seepage are very important to determine before the construction of a dam or even after the construction of the dam for maintenance work.
Electrical resistivity method is used to determine the amount of seepage and depth of seepage.
As a civil engineer, it’s our responsibility to provide higher safety.
Seepage under the embankment is very much dangerous as compared to concrete dams because embankments are built on a very soft material which is easily scoured and it is very vulnerable for the influence of water.
On other side concrete dam, is built on hard strata and even the defective dam which not the endangered by passing of water from the underside.
Following are the methods for controlling seepage
What is the difference between black cotton soil and clay?
Black Cotton soil ; Black Cotton Soil is a heavy clayey soil, varying from clay to loam.The black color in black cotton soil is due to the presence of Titanium Oxide in a little concentration. Generally, it is light to dark appearance. Found in central and southern parts of India. Clay SOIL; Clay soRead more

Clay SOIL; Clay soil is composed of very small fine particles and not much organic in nature. It contains clay minerals which, when get wet, develops plasticity. Clay minerals have hydrous Aluminium phyllosilicates.

Permeability of soil is an important property of soil study as a civil engineering point of view. Permeability of a soil is the property to allow water to pass from a series of pores. Following are some factors which affect the permeability Shape and size of the soil particles Temperature and climatRead more

See lessWhat is negative pore water pressure in soil?
The pressure is zero when the soil voids are filled with air, and is negative when the voids are partly filled with water (in which case surface-tension forces operate to achieve a suction effect and the shear strength of the soil is increased).

Generally, shear strength is a term used in soil mechanics to describe the magnitude of the shear stress that a soil can sustain. The shear resistant of soil is a result of friction and interlocking of particles, and possibly cementation or bonding at particle contacts. Due to interlocking, particulRead more
Generally, shear strength is a term used in soil mechanics to describe the magnitude of the shear stress that a soil can sustain. The shear resistant of soil is a result of friction and interlocking of particles, and possibly cementation or bonding at particle contacts. Due to interlocking, particulate material may expand or contract in volume as it is subject to shear strength. If soil expands its volume, the density of particles will decrease and the strength will decrease; in this case the peak strength would be followed by a reduction of shear stress.

Braced excavation is a method where deep excavations with straight vertical faces are laterally supported by a sheeting and bracing system until the structure is built.
In deep excavations creating a safe slope on the excavation face just for safety is generally not feasible due to high cost, inabundance of space and other structures present nearby. So, the excavation is temperorly supported by sheets/walls and struts, which are removed individually when their requirements cease. Relatively flexible sheets/walls are placed against excavation walls and supported by horizontal struts which in turn resist the earth pressure in compression.
Some methods are vertical timber sheeting, shoring, steel sheet piling, soldier beams and also tiebacks.
These structures might not be removed later but they may or may structurallynot be structurally important apart from offering temperorly lateral support. For example, tie backs support excavations and also replace permanent retaining walls.
