Dual-Control Method to Determine the Allowable Filling Height of Embankment on Soft Soil Ground

In order to plan rationally the construction process of embankment on the soft soil ground, the information construction technology to determine the allowable filling height of embankment was proposed, which is based on slope stability and allowable settlement after construction. The correlative program had been developed. The method of effective consolidation stress was adopted to analyze the stability of the embankment and the enhancement of the sheer strength of the soft ground with its consolidation process was taken into account. Method that modifies the degree of consolidation using the monitored settlement was proposed too. All these were performed to the practical case and the results show that the dual-control method proposed is effective and practicable to guild the information-construction of embankment on soft soil ground.
