Abstract

As a country that surrounded by active volcanoes, Indonesia has a very diverse clay soil content. However, in reality, clay soil is an unfavorable condition for construction activities because of its low-level of stability. Therefore, when the clay soil receives a static load on it, the soil will slowly have a settlement due to the dissipation of pore water. This settlement usually occurs over a very long period of time, thus, it is necessary to do the soil improvement using Prefabricated Vertical Drain (PVD) combined with preloading in order to shorten the time of soil consolidation so that the consolidation process becomes faster. Soil settlement analysis is calculated using two soil parameters derived from the NSPT correlation data and laboratory test data to determine the most efficient soil parameters. Furthermore, a theoretical soil improvement analysis was carried out by comparing Baron's theory and Hansbo's theory and using the Settle3D analysis program. The analysis results show that the calculation of consolidation settlement using soil parameters from laboratory test results has the closest value to the actual results in the field with a efficiency of 91%. Meanwhile, for soil improvement, the most effective PVD design was chosen using the Hansbo theory with a triangular installation pattern and a spacing of 150 cm combined with a gradual embankment.
利用预制DRAIN方法进行土壤修复的有效设计
作为一个被活火山包围的国家,印度尼西亚的粘土含量非常多样化。然而,在现实中,由于粘土的稳定性较低,对建筑活动不利。因此,当粘土受到静荷载作用时,由于孔隙水的耗散,土体会缓慢发生沉降。这种沉降通常会持续很长时间,因此,有必要采用预制垂直排水(PVD)结合预压的方法进行土壤改良,以缩短土壤固结时间,使固结过程更快。土壤沉降分析是利用NSPT相关数据和实验室试验数据得出的两个土壤参数来计算的,以确定最有效的土壤参数。通过对Baron理论和Hansbo理论的比较,利用sett3d分析程序进行土壤改良理论分析。分析结果表明,利用室内试验结果的土体参数计算固结沉降与现场实际结果最接近,效率为91%。同时,为了改善土壤,采用Hansbo理论选择了最有效的PVD设计,采用三角形安装模式,间距为150厘米,并结合渐进式路堤。
