The dust that can be dangerous for the above applications is, according to the NFPA (National Fire Protection Association of USA), any finely divided solid material that is smaller than 420 mm [8] The most important parameters to evaluate the risk of explosion in a pharmaceutical industry are [9]: · Minimum Ignition Energy (MIE) · Minimum Ignition Temperature (MIT) · Thermal Stability Explosion Severity (Kst) · Minimum explosive concentration (MEC): Most of the active pharmaceutical ingredients and excipients used in the pharmaceutical industry have minimum explosive concentration (MEC) in the range of 25 to 60 grams/m3.

As shown in Fig. 1, the cushion is a layer of soft material, which is placed between the raft and the soil surface, to adjust stress distribution on the raft.
The length of pile is 5 m, the corresponding spacing of pile is 40cm, 50cm and 60cm, the material of cushion is coarse sand.
According to different material of soil and highway, the model is divided to several groups, containing fine sand, silty clay, mucky soil, cushion, embankment and pavement.
