Shrinkage in Concrete01:27

Shrinkage in Concrete

84
Shrinkage in concrete is primarily due to water loss from evaporation, hydration of cement, or carbonation, leading to a reduction in volume. The volumetric contraction results in volumetric strain in concrete. However, in practice, shrinkage is measured as linear strain, which is one-third of the volumetric strain.
When concrete is still in its plastic state, it can undergo a decrease in volume by about 1% of its absolute volume. This decrease is known as plastic shrinkage. It arises either...

Design Example: Maintaining Level of an Embankment

52
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

40
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Summary

Coal mining subsidence can damage infrastructure. This study used particle image velocimetry (PIV) to analyze strata movement, finding that thicker and shallower coal seams cause greater subsidence, aiding disaster prediction.

Area of Science:

  • Geotechnical Engineering
  • Mining Engineering
  • Earthquake Engineering

Background:

  • Coal mining subsidence poses significant risks to surface structures and infrastructure.
  • Dynamic analysis of mining-induced subsidence is crucial for predicting and mitigating potential failures.
  • Existing methods for understanding subsidence mechanisms require further refinement for accurate prediction.

Purpose of the Study:

  • To investigate the strata movement and subsidence patterns caused by coal mining.
  • To analyze the influence of excavation thickness and coal seam depth on subsidence magnitude.
  • To evaluate the effectiveness of particle image velocimetry (PIV) in studying coal mining subsidence.

Main Methods:

  • Utilized prototype and indoor physical model similarity experiments.
  • Applied the particle image velocimetry (PIV) technique to visualize and quantify strata movement.
  • Varied excavation thickness and coal seam depth in the experimental models.

Main Results:

  • Demonstrated a direct correlation between increased coal mining thickness and greater subsidence magnitude.
  • Observed that shallower coal seams result in more significant surface subsidence.
  • Quantified the spatial distribution and magnitude of overlying strata movement during mining.

Conclusions:

  • Particle image velocimetry (PIV) is an effective method for studying coal mining subsidence mechanisms.
  • The findings provide valuable insights into predicting subsidence patterns and potential infrastructure failure.
  • Combining PIV with field monitoring data can enhance the accuracy of subsidence prediction and disaster mitigation efforts.
