| 摘 要： | 饱和软粘土含水率大、渗透性差,强夯处理时,超孔隙水压力不易消散,常规的排水措施效果不佳,而电渗降水已经被证明是一种有效的软粘土排水措施。本文提出了将电渗降水和强夯法相结合的地基处理方法——双控动力固结法,进行了双控动力固结法的处理试验,并与不降水强夯法和井点降水强夯法进行对比分析。结果表明,电渗法可迅速降低地下水位和地基土含水量,有效避免"弹簧土"的产生,提高单点夯最佳夯击能;可有效抑制夯后超孔隙水压力的急剧上升,并促进超孔隙水压力快速消散;在降水速度和土性改良方面,电渗降水优于井点降水。因此,应用双控动力固结法处理软粘土,有着很显著的加固效果。 |

| Abstract: | High water content and poor permeability of saturated soft clays lead to difficult dissipation of excess pore water pressure in the forced tamping process;for the saturated soft clays,conventional drainage measures are inefficient while the electro-osmotic method has proved to be an effective drainage measure.A double-control dynamic consolidation method,the combination of the electro-osmotic method and the forced tamping method,is proposed in this paper for strengthening soils,and it has been compared with... |
