liquefaction of soil | how does liquefaction occur

Liquefaction Of Soil:

is the phenomenon in which the soil behaves like liquid means it losses its strength and stiffness due to intense shaking of an earth quake.
;Liquefaction of soil


How does liquefaction of soil occur [REASONS]:

liquefaction of soil occurs in saturated soil in which water is entrapped in the pores means pores are filled with water. This water exert pressure of the particles of soil but in first this pressure is small but when earthquake occur the water pressure increases and hence due to this increase in pressure the strength  contact bond between the particles decreases. So by this way the soil strength decreases and the soil losses its ability to support load.


Liquefaction of soil

Conditions for liquefaction of soil:

Following are some conditions for liquefaction of soil:

  • loose granular soil
  • saturation of ground
  • strong shaking

Effects of liquifaction of soil:

As we know due to liquefaction settlement occurs in soil and due to this settlement alot of problems also starts in soil.
  • Sand boiling occurs in soil 
  • Due to liquefaction the big structures Dams and retaining structures fails 
  • Land sliding problem also occur due to the liquefaction of soil phenomenon
How to reduce the liquefaction phenomenon:

we can not totally remove the effect of of liquefaction in every soil which is saturated this phenomenon occur in some cases in a large amount and in some cases in a very little amout so we can took some steps to reduce the liquefaction phenomenon
  • Try to avoid the liquefaction susceptible soil for your project
  • if we can`t change our site place which have chances to get the liquefaction phenomenon so then try to make a Structure that can bear the effects of liquefaction
  • There is a lot of techniques now to improve our soil qualities by this way we can control liquefaction.
  • Another method is to mix  some clay with your soil to reduce liquefaction of soil

Best Civil engineering softwares

ALL BEST CIVIL ENGINEERING SOFTWARES: As we all know that this is the age of skills.. Due to skills a person is highlighted in a group of people.. A department who require a person for a job must search something in the person who wish to get this  job. Now a days engineering jobs are not easy because the world is transferred from old methods to new concepts. According to new theories it is necessary for an engineers to import some skills in his own life. An engineer must be professional in his work. According to me now a days the software has a big role in the development of world. So an engineer must be skill full in software. So i am going to write some softwares important for a civil engineer. Best Softwares  for a Civil engineer: AutoCad: for the designing a plan autocad is one of the best software. Also used for dafting..                     Revit for building information modeling revit is one...

how does a drinking water treatment plant work?

Water Treatment Plant: The process of making water suitable for use is called water treatment As all living things require water for their lives also the use of water in industries and in other practical works is significant. And we all know that at every palace in the world the pure water or clean water is not available so we use Some techniques to improve the water quality.  One of them is a water treatment plant. The concept of Water treatment plant is now a days widely used by many of countries. Although its initial cost is very high but its performance is very good. So now I am going to share with you that how this work.. Conventional water treatment plant: The flow chart of conventional water treatment plant is given below check out this Source Intake structure → Primary  sedimentation → coagulation and flocculation → Secondary sedimentation → Filtration → Disinfection   → Storage/Distribution. Source: Source is the place from where we get th...
