Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

In light of the disaster in Shizuoka, I hope everyone will learn a little more about soil.<\/p>\n

\"Shizuoka<\/p>\n

Here's a simple explanation of why soil erodes.<\/p>\n

\n

But that's beside the point.<\/p>\n

About Cliffs (For the General Public)<\/a><\/p>\n

I'm continuing to write about the cliff incident from the other day for a general audience.<\/p>\n

Pros, feel free to skip this. lol<\/p>\n

 <\/p>\n

Don't you ever wonder what soil is all about!?<\/p>\n

It makes you wonder, doesn't it!<\/p>\n

I think we professionals and civil engineers generally have a pretty good idea of what's going on, lol.<\/p>\n

Because I'm always messing around with dirt.<\/p>\n

 <\/p>\n

So, what exactly is soil...? According to the book...<\/p>\n

A mixture of soil particles (solid) + water (liquid) + air (gas)<\/span><\/strong><\/span><\/p>\n

This is soil.<\/p>\n

And that \u201cmost dangerous saturated state\u201d that came up the other day is, in fact,<\/p>\n

Soil particles (solid) + water (liquid)<\/span><\/strong><\/span><\/p>\n

What?!<\/p>\n

A state in which there is no air left is called a saturated state.<\/span><\/strong><\/span>That's what they say.<\/p>\n

Conversely, if air is present, it is said to be in an unsaturated state.<\/p>\n

\"\u571f\"<\/p>\n

This saturated condition is what causes surface slippage.<\/p>\n

On the cliffSoil particles (solid) + water (liquid)<\/span><\/strong><\/span>That's the only option, right?<\/p>\n

So, the soil particles are carried along by the water and flung away, causing the cliff to collapse with a huge crash.<\/p>\n

So, I think you can see that it\u2019s important to drain the water to create an unsaturated condition.<\/p>\n

The more I learn about cliffs, the scarier they become\u2014but they\u2019re also fascinating (or is that just us slope specialists?).<\/p>\n

If you know about it, you can take steps to deal with it.<\/p>\n

Whether or not you take precautions is your own responsibility, but please be very careful, as landowners also bear certain responsibilities.<\/p>\n

See you later.<\/p>","protected":false},"excerpt":{"rendered":"

With so much free time on my hands, I started a blog. I\u2019ve been sharing my expertise on slope stabilization and answering all kinds of questions. As a result, I\u2019ve seen an increase in inquiries, questions, and orders from slope stabilization contractors, general contractors, and other major construction firms. My traffic on Ameblo grew to a reasonable level, so I decided to move on from Ameblo by acquiring my own domain in order to create a more user-friendly blog. I plan to continue sharing all my expertise openly and honestly here.
