Instability evaluation of rubble mound for breakwaters subjected to tsunami-induced overflow and seepage flow
Autor: Zentaro Furukawa, Yasuyuki Nakagawa, Kouki Zen, Kiyonobu Kasama
Publikováno v: Soils and Foundations. 60(Issue 6):1532-1545
This paper presents a formula to estimate the stable weight of a rubble mound for breakwaters, considering the tsunami-induced overflow and seepage flow, based on the theoretical force balance among the frictional resistance of the rubble mound, the

Finite Element Modeling of Compaction Grouting on its Densification and Confining Aspects
Autor: Neha Shrivastava, Kouki Zen
Publikováno v: Geotechnical and Geological Engineering. 36:2365-2378
Compaction grouting method called as CPG is becoming popular as a ground improvement technique due to its wide variety of applications and several advantages. However, so far, the application of the method has been mainly dependent on field tests, pr

Controlled Curved Drilling Technique in the Permeation Grouting Method for Improvement Works of an Airport in Operation
Autor: Kouki Zen, Kentaro Hayashi, Rouzbeh Rasouli, Seiki Takano
Publikováno v: Procedia Engineering. 143:539-547
Improvement of the ground under existing structures against liquefaction is not easily possible. A new controlled curved drilling method is developed to apply the permeation grouting of chemicals to the liquefiable ground under existing structures. T

Modeling of Compaction Grouting Technique with Development of Cylindrical Cavity Expansion Problem in a Finite Medium
Autor: Sanjay Kumar Shukla, Kouki Zen, Neha Shrivastava
Publikováno v: International Journal of Geosynthetics and Ground Engineering. 3
The compaction grouting (CPG) method is relatively a new ground improvement technique for mitigating the liquefaction problem. In this technique, a stiff mortar is injected under high pressure that displaces and compacts the surrounding soil. Though

An Experimental Study of Compaction Grouting on Its Densification and Confining Effects
Autor: Kouki Zen, Neha Shrivastava
Publikováno v: Geotechnical and Geological Engineering.
Compaction grouting (CPG) involves the injection of high viscosity mortar-type grout under relatively high pressure that displaces and compacts the soil in-place. Many case studies around the world prove the effectiveness of CPG to treat liquefiable
