About designation of special caution area based on the prevention of earth and sand disaster method

The last update date:
We appoint the earth and sand disaster special caution area of the prevention of earth and sand disaster method in Saga.
System of building certification is applied about building having living room at place except city planning area and associate city planning area in the earth and sand disaster special caution area. In addition, it is necessary to do structure of building with structure that is safe from power that nothing special accompanied with collapse of steep slope gives to building.
 

Application of building certification system

 It is necessary especially to receive building certification whether it is when building (new construction, the enlargement, reconstruction) does building having living room in caution area that structure of building meets standard for prevention to reduce the earth and sand disaster before the start of construction.

※Necessity or not of building certification, way of thinking With new window(49KB, PDF file) of structure proof stress standard application

 

Structure of building in special caution area

  About structure standard, it is established for each type (collapse, mud flood, landslide of steep slope) of natural phenomenon to become outbreak factor of the earth and sand disaster by 3 and Ministry of Land, Infrastructure, Transport and Tourism notification No. 383 of Building Standard Act enforcement order Article 80.

When we greatly divide and do with structure method by specifications regulations mainly to become safe from power (shock) assumed that it acts to building by natural phenomenon that structure of building having living room becomes origin of the earth and sand disaster, we may do with structure method to confirm safety by structural calculation. (when we establish the gate by regulations of 3 provisos of ※ Building Standard Act enforcement order Article 80 or wall, all become excluded.)

In addition, power (shock) assumed to act on outer walls of building calculates based on number appointed with type of natural phenomenon in particular for each caution area.

 

(1) When we assume structure method by specifications regulations

About outer wall, buttress, structurally basic or main part, it is thing by constant structure method (thickness of wall, quantity of reinforcing rod, limit of opening) that accepted power (shock) assumed that we act on outer walls of appointed building.

(2) Structure method to identify safety by structural calculation

For power (shock) assumed that the earth and sand shock calculation acts on outer walls of building, we confirm what the outer walls concerned do not destroy based on materials strength regulations.

 

  Please see Anzu (Saga river, erosion control geographical information system) We open with the other window(external link) about the designated situation of caution area in particular caution area.

 We can inspect matter about shock necessary for structure regulation of designated area figure and building in each engineering works office management section or Saga prefectural office River & Sediment Control Division (management first charge).
