The determination of stability safety factor of high slope rock-fill embankment using Bishop method;

Aiming at a high slope embankment research,through exploration of field geology relief and traffic situation,the lacing retaining wall finite modes of two dimension hierarchy oblique slopes were built.

Rockfill stuff and subgrade soil should be studied on settlement rule for high rockfill embankment respectively,for the differences of the pressurized state and settlement rule.

Currently, the compaction characteristic and compaction mechanism research of rockfill need to be studied thorough; the high rockfill embankment was fill high, the deadweight was heaviness, the settlement mechanism was complex, the settlement was great, the settlement forecast of high rockfill embankment need to be discussed farther; m.

The planning of changing Longmentang bridge between Chongqing Qijiang and Wansheng arterial highway into filling-stone embankment can resolve the problem of wasted soil,reduce engineering cost and benefit environment protection.

Study on variable-weight combined forecasting method of the settlement in high rock-filled embankment;

Study on the Creep Model & Its Parameter s Back Analysis by Finite Element Method of Creep Deformation and Their Application for High Rock-filled Embankment;

To solve the problem of the settlement of high rock-filled embankments during and after construction for the roads in Southwest China, the settlement of subgrade was calculated by considering the nonlinear character of the subgrade under high stone fill (high stress level) and its actual stress path, based on the actual situations of engineering and methods known to the engineering circle.

Studies on structural performance of embankment slopes reinforced by geogrids with model tests;

Based on necessity of erosive protection for embankment slope and deficiency of research on erosion calculation model of slope, the hydraulics particularity of embankment slope is analyzed and the processes of water-erosion of slope are described on energy by the conservation and transform principle of master energy.

Field investigation of soil erosion was conducted on embankment slopes of both Qinhuangdao-Shenyang special line of passenger trains and Jiaozhou-Xinyi railway after precipitation, and factors leading to great difference of erosion degree between the two experimental plots were analyzed.
