Hi, I’m Kkoogongnam. Today we’ll break down Darcy’s law in the simplest, most practical way — the way you actually use it in soil mechanics and groundwater flow. (vs seepage velocity) If you understand just three things, you can solve most seepage/flow-through-soil problems: 1) Bernoulli Equation → Total Head (Energy of Water) From fluid mechanics, … Read more
Hello. This is Kkoogongnam. Recently, not only Korea, but also India and other countries have been experiencing heavy rainfall. I hope everyone is safe. While watching the news, I thought about why landslides occur when it rains on civil engineering perspective. A landslide is a phenomenon in which soil moves down a slope, such as … Read more
Hello! This is Kkoogongnam. In our previous discussion, we briefly explored ground improvement methods for weak soils. (Please refer to the previous post for more details.) Today, we’ll enhance our understanding by providing concise explanations for each method. Before We Start: Understanding Clayey and Sandy Soils. 1. Clayey vs. Sandy Soils Accurate definitions can be … Read more
Hello, this is Kkoogongnam. If you are studying civil engineering, understanding “soil” is essential. While concrete is also important, knowing the engineering properties of soil is crucial for understanding bearing capacity and ground settlement. First, soil can be classified into gravel, sand, and clay based on particle size. To understand the engineering properties of soil, … Read more
Hello, this is Kkoogongnam. Today, I will discuss the types and characteristics of Ground Improvement Techniques. When constructing high-rise buildings or factories, significant load-bearing capacity is required. If the soil is weak, various techniques are employed to improve it. Let’s outline these techniques as follows. 0. What is Weak Ground? Weak ground is characterized by … Read more
