Abstract

In an effort to determine the residual strength from the laboratory tests, a new type of tests termed “constant-volume triaxial test” was performed on non-saturated specimens of silty sand prepared at varying water contents. The results of the tests disclosed that the water content or saturation ratio is a key parameter governing the residual strength of the non-saturated soil tested in the above manner. Back-analysis was also made to determine the residual strength that might have been mobilized in the landslide triggered at Tsukidate at the time of the May 26, 2003 earthquake. The comparison of these two data showed a reasonable degree of coincidence, indicating that the proposed method of the laboratory triaxial tests would be a promising means for estimating the residual strength of given soils.

Abstract

Widespread damage to lifeline systems occurred as a result from the Kumamoto Earthquakes that initiated on April 14, 2016. Interruption to the water, gas, and electric power supply affected thousands of people. Landslides and surface rupture caused significant damage to transportation systems, especially roads and bridges. This paper provides an overview of observations and information gathered by US researchers (sponsored by Geotechnical Extreme Events Reconnaissance Association), Japanese researchers, and others regarding water supply damage. Emphasis is placed on the largest water authority in the region of the earthquake, Kumamoto City, including damage metrics for various pipe materials and diameters. The greatest damage occurred at valves and other fundamental mechanisms of large diameter pipelines. Pipelines constructed of ERDIP and HDPE performed most favorably while steel and cast iron pipelines were shown to be the more vulnerable. A liquefaction-induced lateral spreading site at which pipeline damage occurred is identified for further study.

Abstract

A major earthquake with a magnitude (MJMA) 6.5 foreshock and a MJMA 7.3 main shock occurred at 1:25 on April 14 and 21:26 on April 16, 2016, respectively, in the Kumamoto region. According to the Kumamoto Castle research center, the reported damages to Kumamoto Castle included 23 important cultural properties, the 27 reconstructed structures and 523 stone wall deformations. Thirty percent of all of the stone walls were damaged. The stone wall foundation used two different construction techniques from the Kato age and Hosokawa age. The damage patterns with respect to the shapes of the stones in the walls were investigated and compared. The damaged stone walls which related to the main shock, were mainly constructed Hosokawa ages. In addition, the damage patterns in the reinforced concrete reconstructed Castle Keeps (Tensyu) / turrets (Yagura) and existing historical wooden structures were compared.

Abstract

In the 2016 Kumamoto earthquake, a lot of landslides, slope failures and debris flows occurred in mountainous regions around Mt. Aso. Most of the failed slopes were located near the earthquake faults caused strong vibrations. Although there was very little rainfall before the earthquakes, debris flows occurred along the mountain streams and eventually travelled long distances. It is noted that volcanic soil, being fragile and sensitive to disturbances, was widely distributed within the affected area. In this research, the conditions of large-scale failure, landslide, and debris flow are investigated to clarify the characteristics and history of earthquake-induced sediment disasters in the volcanic regions based on the results obtained from our investigation.

Abstract

At 21:26 JST on April 14, 2016, an earthquake with a Japan Metrological Agency Magnitude (MJMA) of 6.5 struck Kumamoto Prefecture, Kyushu, in southwestern Japan. This earthquake was followed by a larger earthquake with an MJMA of 7.3 at 1:25 JST on April 16, 2016. These were the most severe earthquakes to occur in Japan since the Tohoku earthquake in 2011. The hypocenters of the strike-slip MJMA 6.5 foreshock and MJMA 7.3 main shock and, along with the aftershocks, were widely distributed along the active Futagawa-Hinagu strike-slip fault. This paper first presents the distribution of the liquefied sites during these earthquakes and their effects on the surrounding buildings and infrastructure. Next, the distance from the epicenter to the farthest liquefied site is compared with past Japanese earthquakes, followed by a discussion on the intensities of the ground motion that caused the liquefaction. Finally, the land conditions and soil profiles where severe and widespread liquefaction occurred are investigated.

Abstract

The 2016 Kumamoto earthquake with a moment magnitude of 7.0 (Japanese intensity = 7) that struck on April 16 brought devastation in many areas of Kumamoto Prefecture and partly in Oita Prefecture in Kyushu Region, Japan. The earthquake preceded a foreshock of magnitude 6.5 (Japanese intensity = 7) on April 14. This paper summarizes the damage brought to geotechnical structures by the two consecutive earthquakes within a span of twenty-eight hours. The paper highlighted some of the observed damage and identifies reasons for such damage. The geotechnical challenges towards mitigation of losses from such earthquakes are also suggested.

Abstract

This paper is intended to describe that the nonlinearity of seismic response for soft deposits is associated with the cyclic degradation of strength and stiffness in shallow deposits of cohesive volcanic ash soils, which caused devastation to residences. Using the simplified methodologies proposed previously by the authors, which incorporate cyclic strength and stiffness degradation characteristics of saturated cohesive soils, prediction was conducted for residential settlement and lateral deformation of residences with retaining walls founded on and against a shallow layer of cohesive volcanic ash soils. A chart for construction management incorporating the results in terms of earthquake-induced settlement vs. lateral deformationsettlement relations predicted the use of the methodology described above. Results suggest that residences are likely to sustain severe damage when the normalized excess pore pressures generated during the earthquake extend to about 0.7. Results also show that damage to retaining walls was also associated with earthquake-induced strength degradation of backfill soils.
