METHODS FOR THE ARRANGEMENT OF IMMERSED TUBE TUNNELS DURING CONSTRUCTION BASED ON STRUCTURALLY UNSTABLE SOILS by E. N. Kurbatskiy, N. V. Kupchikova

“…Tunnels are less susceptible to seismic impacts, since, unlike ground structures, they don't experience resonance phenomena. When seismic waves pass, the tunnels are deformed in the same way as the surrounding soil massif (if the soil is solid), or much less (if the soil is weak). …”

“…However, seismic measurements cannot always provide a comprehensive image of lake-bottom sediments, e.g., due to lacking seismic contrasts between geological units or high attenuation of seismic waves. Here, we developed and tested a complementary method based on water-borne electrical-resistivity tomography (ERT) measurements. …”

Liquefaction test and seismic load simulation of saturated sand subgrade with different salt contents by Lei Zhang, Lei Zhang, Lei Zhang, Hongxia Qiao, HongZhuang Shi, Weizhong Ma, Shanglin Song, Hanghang Wang

“…After the indoor geotechnical test, the soil samples were reshaped, The liquefaction test of saline saturated sand was carried out by using the GDS dynamic triaxial device to simulate seismic load to investigate the liquefaction mechanism of saturated sand under different salt contents and verify the liquefaction discrimination standard, then based on the data of dynamic elastic modulus, dynamic shear modulus, damping ratio coefficient, and soil density obtained from previous soil tests and dynamic triaxial tests, four subgrade models with different salt contents were constructed using ANSYS simulation software according to actual engineering, and the settlement and deformation of the subgrade were analyzed by inputting EL-concrete seismic waves. The results show that the maximum value of axial stress of saturated sand decreases with the increase of salt content; the load vibration times of saline saturated sand reaching the initial liquefaction state are more than that of common saturated sand; the higher the salt content, the weaker the liquefaction resistance of saturated sand; when the pore pressure ratio coefficient reaches 1, the axial double amplitude strain εd of the soil also reaches 5%, and the soil reaches the initial liquefaction state; the area of shear stress and strain hysteresis curve increases with vibration load, and the elastic modulus decreases gradually; the shear dilation and compaction effects occur in each hysteresis cycle, and the former is greater than the latter, the research results have guiding significance for similar studies in highly saline saturated sand areas.…”

Evidence of strong long-period ground motions of engineering importance for Nankai Trough plate boundary earthquakes: comparison of ground motions of two moderate-magnitude earthqu... by Yadab P. Dhakal, Wataru Suzuki, Takeshi Kimura, Nobuyuki Morikawa, Takashi Kunugi, Shin Aoi

“…An examination of the existing subsurface velocity model suggested that the difference in the relative location of the two events with respect to the thick accretionary prism of low seismic velocity most probably caused the comparable amplitude of the seismic waves at those periods. As a result, we posit that the values of Mj are equal for the two events because Mj is estimated using the displacement amplitude of ground motions at periods smaller than about 6 s. …”
