Figure 18. Atom bomb destruction
Refer figure 18 that ranges areas include the surface structure is collapsible for a yield of detonation ranges. It will protect the atomic explosion is created the substructures shelters into the required depths. Most of the subsurface shelters are consists of shielding in an exterior surface because of the protection of gamma rays. The shield army trench base concrete bunkers are the 10-times thickness of the material. It reduces the stopped 50% of the radiation effects. Thus a practical fallout the shield is a 10 halving-thickness of packed earth. It reduced the gamma rays average of approximate rates in 1024 times. The usual trench army base shelters are partially safe for the radiation effect in and to any times 24-hours attacking strategically conditions. And underground bunkers are shelters is a trench its connections are strong roofs of bunkers (reference analysis previous designs in Table 1, 2, 3 structural components) < 1 m of earth. There is make loaded in 2-sides, and emergency use in one-side of ways. Right angle entranced to exterior inspection rooms go after the beneath to the interior inspection sites, through proper ways. So that the gamma rays are not entered they can travel the straight line. To makes constructed the overburden water ceiling proofs. In case of heavy rains, and provided the proper drains in an above the surface of the trench bunkers because the wide reasons are not affected the sub-surface of bunkers roofs. Are another technique is handled in heavy rainfalls situation, there are plastic shut provided buried a few inches depth below the surfaces and held down the rocks, mud-dust, rice husk ash are poured to closed compacted the sheets. Types of actions are followed to protected high percolation of bunker site zone area. Blast doors are designed in a suitable prevented the heavy shock waves of atomic detonation. Blast doors it will works in deformation of bend and after original position.
Locations of the attacking and activation of bunkers are below the ground levels and points of borders areas like lines of control sites. Presented in critical war zones areas. the thickness of the structural members is the effectiveness and most toughness of effective shield protections. The army bunkers area must not view fallout covered ground that is closer than 2 km.
Content of bunkers is:
DC battery is must be needed for shelters.
Conclusion
Advanced Planning and Designing of Multi-Purpose System of Army Trench Base of Concrete Bunker project paper shows the outcomes of the design in terms of drawing and result analysis. In the design projects, And advanced innovative structural systems to attain the stated. An objective such as durability and economical with defence construction safety of appealing appearance. This bunker planning in 2-ways systems, One is the inspection position and the same way to another is attacking positions for the suitable site of warhead conditions. It most strongly and compacted concrete designed. And this bunkers is intended in heavy concrete wall frames for resistances, likes earth pressures and heavy explosive projectiles. For the most part, important things of underground shelters are not identified the enemies global visual satellites images, And it secured developed underground bunker construction mission implementation higher values. And army trench base concrete bunkers systems is successful use for purposely in emergencies defended to attack destroyed the enemies target points.
