<<Model studies of a circular footing supported on
geocell-reinforced clay>>
Abstract: The potential benefits of geocell reinforcement in soft clay foundations have been studied by a series of
laboratory-scale static load tests on a rigid circular footing placed on a fill surface. Parameters of the test program
include depth of placement of the geocell layer, width and height of the geocell layer, and influence of an additional
layer of planar geogrid at the base of the geocell mattress. With the provision of geocell reinforcement, the loadcarrying
capacity of the soft clay foundation can be improved by a factor of up to 4.8 times that of the unreinforced
soil. Heaving of the soil can be reduced substantially by providing geocell reinforcement of sufficient height and width.
Further improvement in performance could be obtained with the provision of an additional layer of planar geogrid at
the base of the geocell mattress.

摘要：潜在好处的土工格室在加固软土地基已研究了一系列
实验室规模的静载试验对僵化的通告的基础上放置在填补表面。参数的测试程序
包括深入就业的土工格室层，宽度和高度的土工格室层，和影响力的额外
一层平面土工格栅在该基地的土工格室的床垫。与提供的土工格室加固， loadcarrying
能力的软粘土地基可以改善的一个因素高达4.8倍的无
土壤。冻胀的土壤，可以大幅减少土工格室加固提供足够的高度和宽度。
进一步改善，表现可以得到与提供一个额外的层平面土工格栅在
该基地的土工格室的床垫。
导言
土工格室加固是最近开发的技术
在该地区的土壤加固和包括一个三维，
高分子，蜂窝样结构的填充
细胞在相互关联的关节。因为它的三维
性质，土工格室提供了一个全面的隔离
以封装的土壤，和相互关联的填充
细胞形成一个小组的行为像一个大垫子和散布
适用于负荷超过1扩展面积，而不是直接在
联络点，导致一改善，整体
表现的基础。几项调查都
据报，突出的有益利用土工格室加固
在建设的基础和河堤
（例如，的REA和米切尔， 1978年;米切尔等人。 1979年;
清水和干友彦1990年;考兰和黄1993年;詹纳等
基地。 1988年; krishnaswamy等人。 2000年;短跑等人。 2001年，
2001 ， 2003年， 2003年） 。土工格室是传统的填充
与免费的排水材料像沙子或砾石。在该案件
不提供这么好的质量附近土壤建设
网站，当地现有的粘性土，可用于如发现
适当的。本文报告的结果，从一系列的实验室
模型试验进行，以确定性能
改善通告的基础上，由于提供
土工格室加固在背后的软粘土层。
