“…In the past period, scholars at home and abroad have carried out a large number of model experiments [1][2][3][4][5][6][7][8] and numerical simulations [9][10][11][12][13][14][15][16][17] on the rainwater infltration of embankment soil, most of which are based on the traditional research of uniform penetration of embankment soil surface and slope and constant rainfall intensity, studying the safety of embankment slope and the characteristics of rainwater seepage, and mainly focusing on preventing serious collapse accidents on embankments. However, the uneven settlement of the embankment caused by rainfall [18][19][20][21][22][23][24] is a more common form of destruction in the actual use process.…”

The rainfall often causes changes in the physical performance of the embankment, which leads to disasters such as embankment collapse and road surface settlement and cracking. Past research has tended to be limited to traditional embankment seepage models and is mostly based on the assumption that surface precipitation is uniform and rainfall intensity is constant. To adapt to the changes and development of the times, based on the water leakage mode of the flexibly assembled highway embankment, a new rainfall calculation model of the reinforced soil embankment is constructed and combined with the solid-fluid coupling physics theory, the sedimentation amount and slope stability of the embankment are analyzed at multiple levels, the mechanical properties of the new embankment under rainfall conditions are summarized, the factors affecting the settlement of the embankment and the stability of the slope are explored, and the reference model is provided for the construction of the new embankment, and the existing construction process is improved through multilevel cause analysis. We improve and develop the existing theoretical system to reduce the probability of road diseases, improve the efficiency of road construction, and reduce the cost of road maintenance.

“…Collapses of embankments have occurred due to heavy rainfall. On September 7, 2005, the rain by a typhoon brought an embankment collapse of expressway in Iwakuni of Yamaguchi [4]. It was 520 mm of accumulative precipitation, and 64 mm of maximum hourly precipitation.…”

Collapses of embankments have occurred due to heavy rainfall. It is very important to understand the strength properties under various unsaturated, partially saturated and fully saturated conditions of compacted materials. So, a series of unsaturated and saturated triaxial compression tests for compacted soils have been conducted to understand the effects of drainage and saturation on undrained strength. Soil samples were collected from several road embankments to carry out the experiments. The undrained (CU) strength of compacted material decreased with increase in the degree of saturation. Especially, the strength decreased from partially saturated condition to fully saturated condition was remarkable. The decrease of the materials with volume contractive behaviour was appeared clearly.
