The main goal of each laboratory stand is to stimulate a high intensity cavitation phenomenon and to evaluate the cavitation resistance of new structural materials.
The assessment of cavitation resistance of structural materials is also carried out on devices simulating the impact of microjet taking place in the final phase of the cavitational bubbles implosion.

Introduction
The conventional tower packed with fills or packings material has a great surface area, as shown in Fig.1(a).
A common fills material is wooden or fiberglass slats over which the water slowly drips.

There are many diseases in highway tunnel: lining crack, deterioration of lining material, cavities behind the lining and shortage of backfill, shortage of lining thickness, lining deformation, movement, settlement, water leakage, cracking of tunnel portal, forward lean, settlement, disease of ancillary facility, apparent disease of lining(from layer, exfoliation, peeling, honeycomb, surface voids, precipitation).
The eight indexes were proposed which can affect the health condition of highway tunnel, as follows: (1) lining crack; (2)deterioration of lining material; (3)cavities behind the lining and shortage of backfill; (4) shortage of lining thickness; (5) lining deformation, movement, settlement; (6)water leakage;(7) cracking, forward lean and settlement of tunnel portal; (8)apparent disease of lining.
