软土地基对路桥施工的影响分析

基于软土地基的性能和特点,路桥施工往往会遇到棘手的问题,为此针对软土地基工程对路桥施工的影响进行分析。软土地基往往会破坏路桥的稳定性能,对于这一问题,可通过填换改良土来加强其稳定性;路桥施工遇到软土地基时,路面在多数情况下会出现硬化和开裂,加筋法对解决这一问题十分有效;路面沉降是软土地基带给路桥施工的致命问题,加载法可缓解路面下沉,延长路桥寿命。

Numerical modeling for further understanding of roadway junction stability behaviour at deep underground

The review and numerical analysis had been conducted further understand the deformation and failure beahviour of roadway junctions,associated with the different geometrical characteristics,various depth of cover,different mechanical properties around the junction and different construction sequences as well as different construction ad- vances during the roadway junction construction.The results confirme that the simple un- derground structure is more stable than complicated structures,and comparing with dif- ferent geometrical shapes of the two-dimensional roadway junctions,the most unstable one is the four way cross junction,which is the most commonly used in coal mines.On the other hand,the stability of the junction is not linearly related to the depth of cover,the sig- nificant effect only occurred when the depth of cover reached to 1 000 m.Also,with grad- ual degradation of rock mass,the deformation and failure around the junction increased significantly and nonlinearly.The modeling also conductes on the construction sequence for the junction,it is suggested that,during the junction construction,all the additional roadway should be constructed with the direction of moving away from,rather than for- ward to the junction.Finally,the construction advance is also considered for the junction development.It is suggested that when the construction is carried out around the junction, a small excavation advance,such as 1 m or 2 m is adopted for keeping small interruption on the existed roadway or junction.
