摘要
沿海滩涂区为高压缩性、含水量大、承载力低的土构成,把上部填土作为堆载、排水板作为竖向排水体对土进行固结,避免了一般堆载预压所带来的时间长、费用大、工况繁琐、工后大量弃土等问题。方法上运用设计排水体、加载值等获取固结模型,并把固结理论计算与实际现场固结测试结果相比对,得到两者保持基本一致的技术参数和指标。借鉴此方法可先通过设计及理论计算去指导工程实际应用为依据,为工程地基固结应用的一种创新。
The soil is compressible, full of high moisture and often exhibit low strength in coastal beach areas foundation. In consolidation, the time-consuming, expensive, working operation and discarding soil can be avoided if the upper layer of the soil can be used for pressing with the aid of vertical draining plastic plate. Consolidation model can be obtained by observing loading method and the according response. Through the comparison of practice in this consolidation method to theory, we get perfect result that the parameter and in- dex form both are similar. The method is a innovation in practice and can be used to guide practical designing.
