Researches show that the giant debris flow in Hongchun gully started from Ganxipu lateral ditch in the upstream, the materials collected and dam-broke, It collected the material sources of the main ditch, crushed into Minjiang River, joined with the material sources of Shaofan gully debris flow in the river-upstream, blocked river and became dam lake.
A large number of landslide accumulations are distributed on both gully sides and in the gully, which provides a lot of material sources for debris flow.

It has been detected also in cement-based building materials as a negative technological consequence of thaumasite-sulfate attack [1].
In recent years, molecular simulations became attractive also for concrete science.

It had tested dynamic modulus and phase angle of the two kinds of pavement materials under different temperature and load frequency with the help of Simple Performance Tester in order to show the reason, The result shows that, asphalt-rubber concrete has smaller Phase angle at wide temperature as well as frequency changes, it could be one of the main reasons to explain this phenomenon.
In order to show the reasons for the differences, this paper presents the correlations of noise spectrum with viscoelasticity of two kinds of pavement materials, by testing their dynamic modulus and phase angle under different temperature and load frequency.
The difference of viscoelasticity between asphalt-rubber concrete and stone mustic asphalt concrete The materials of asphalt-rubber concrete(ARAC-13) and stone mustic asphalt concrete(SMA-13) were just the same as the pavement of Chang’an avenue paved in 2009.
