Fault may cause not only ground motion but also ruptures and displacement of ground surface where various important lifeline systems have been installed. In Almaty, the largest city in Kazakhstan, many hidden faults are shown in microzonation map for earthquake damage. The Kobe Earthquake of 1995 showed damage of subway system due to severe ground motion. Osaka, Japan, has also hidden fault just beneath the downtown of the city. Recent subway construction in Osaka adapted a design procedure against the fault movement. This paper shows the damage of subway in Kobe during the Kobe Earthquake and describes the fault and geotechnical condition of Osaka with the adopted design as well as basic characteristics of the hidden faults in Almaty known to the authors. 2020-01-01T00:00:00Z http://repository.enu.kz/handle/enu/1343 Methods of testing pile by ASTM and GOST standards Tulebekova, A.S.; Zhussupbekov, A.Zh.; Zhankina, A.K. This paper presented methodic of testing pile by ASTM D1143/D1143M-18 (USA) standard and GOST 5686-12 (Kazakhstan) standard. The methodic of testing piles by these standards have some differences. Discussion of using control equipment, technological features, advantages and disadvantages of aforementioned methodic might be important for understanding the different points. The papers include the results of static tests of piles by using two different standards. This full field scale piling tests were performed in problematical soil ground of construction sites of the new capital Astana (Kazakhstan). 2020-01-01T00:00:00Z http://repository.enu.kz/handle/enu/1342 Influence of deformations of foundations on the stability of building structures Aldungarova, A.; Zhussupbekov, A.Zh.; Abisheva, A. Today, modern technologies effectively carry out work on predicting the stability of structures, determine the optimal solution and choose methods to eliminate the predicted negative impacts on the operation of building structures. The choice of the most optimal one depends on specific tasks. For example, a solid foundation is responsible for the safe operation of the entire building. Accordingly, the structure must be particularly strong and durable. Nevertheless, there are cases when the foundation is weakened and deformed under construction structures, especially those erected a very long time ago. The emergency state and destruction of objects with all the sad accompanying consequences, that is, tragedies with fatal outcomes, which lead to significant damage to the economy of the Republic of Kazakhstan as a whole. It is necessary at the very beginning of planning all stages of work to pay special attention to design, taking into account all deformations of the foundation of the foundations. In general, if we correctly position the correct distribution of the stages of construction of new structures using innovative methods of strengthening, a preliminary analysis of their stability, then in aggregate, after a period of time, we will come to the correct approach to solving this problem. The use of innovative methods for predicting support systems is of particular importance, since the safety of the entire structure depends on the correct and timely implementation of measures. The paper describes the observation for the behavior of soil dams, located on undermined territories, base is exposed to According to the results of observations plotted graphs «Deformations-Settlement». 2020-01-01T00:00:00Z http://repository.enu.kz/handle/enu/1341 Experimental investigations of model pile in freezing and thawing of soil ground Zhussupbekov, A.Zh.; Shin, E. Ch.; Shakhmov, Zh.; Tleulenova, G. This paper includes the short report about static load test of concrete piles (cross – section 4×4 cm and length of 60 cm) in seasonally freezing soil. Based on theoretical methods was calculated the ultimate load-carrying capacity of a pile by a simple equation as the sum of the load carried at the pile point plus the to frictional resistance (skin friction). There are several methods for the determination of the bearing capacity factors. In this paper use Meyerhof’s method, which includes the calculation of ultimate point bearing capacity of a pile in sand and reaches a maximum value at an embed demonstration and also was calculated the ultimate frictional resistance in sand. Based on the values obtained was calculated the allowable pile load. According to Kazakhstan Standard, a safety factor (FS) of SLT is 1.2. In conclusion was presented analysis results of estimation of the bearing capacity of pile foundations in seasonally freezing soil ground. 2020-01-01T00:00:00Z
