Hozirgi kunda yurtimizda foydalanib kelinayotgan suv omborlarining 95 foizi gruntli to‘g‘onlardan barpo etilgan. To‘g‘on tanasi hamda zaminidan kelib chiqadigan filtratsiya jarayonlarining gruntli to‘g‘onlarga ta’sirini o‘rganish dolzarb masala hisoblanadi. Shu bois suv ombori drenajlarida filtratsiya suvlari tarkibini o‘rganish va baholash suffoziya hodisalarining oldini olishda muhim ahamiyat kasb etadi. Tabiiy dala tadqiqotlari davomida Chimqo‘rg‘on suv ombori to‘g‘oni tanasidan bo‘ladigan filtratsiya suvlarini 19 ta gidropostda o‘lchash ishlari amalga oshirildi. Har bir gidropostdan olingan suv namunalarining quruq qoldiq miqdori aniqlanganda, 3a, 4, 7 gidropostlaridagi natijalar yuqori byef suv sathidagi natijalarga juda yaqin bo‘ldi. Qolgan gidropostlarda esa bu ko‘rsatkichlar ancha yuqori darajada ekanligi tadqiq etildi. Olingan namunalarning pH miqdori pH Meters qurilmasida tekshirilib, bir-biridan katta farq qilmayotganligi ma’lum bo‘ldi. Filtratsiya suvlarining loyqalik miqdorini aniqlashda spektrofotometr qurilmasidan foydalanildi va 1, 4, 4a, 5, 6, 7, 7b, 8a gidropostlardan olingan namunalarda loyqalik miqdori yuqori bo‘lgani aniqlandi. Ushbu tadqiqot davomida olingan natijalar shuni ko‘rsatadiki, to‘g‘onlarda filtratsiya suvlari tarkibini o‘rganish va filtratsiya jarayonini baholash muhim vazifalardan sanaladi. Bu orqali gruntli to‘g‘onlarning ishonchli ishlashi ta’minlanadi.

В настоящее время 95 % водохранилищ, используемых в нашей стране, построены из грунтовых дамб. Актуальным вопросом является изучение влияния фильтрационных процессов на грунтовые плотины, которые возникают как на теле плотины, так и на её дне. Поэтому изучение и оценка содержания фильтрационных вод в стоках водоёма приобретает важное значение для предотвращения явлений суффозии. В ходе естественнонаучных полевых исследований на 19 гидропостах были проведены измерения фильтрационных вод, поступающих из плотины Чимкурганского водохранилища. При определении количества сухих остатков в образцах воды, взятых с каждого гидропоста, результаты на гидропостах 3а, 4, 7 были очень близки к результатам к уровню воды на верхнем бьефе. Однако на остальных гидропостах эти показатели были на гораздо более высоком уровне. Уровни pH полученных образцов были проверены с помощью прибора pH Meters, и оказалось, что они не сильно отличаются друг от друга. Спектрофотометрическое устройство использовалось для определения мутности фильтрационных вод, и было обнаружено, что мутность выше в образцах, взятых с гидропостов 1, 4, 4а, 5, 6, 7, 7в, 8а. Результаты, полученные в ходе этого исследования, показывают, что изучение состава фильтрационных вод в плотинах и оценка процесса фильтрации являются важными задачами. Благодаря этому обеспечивается надёжная работа грунтовых плотин.

At present, 95% of water reservoirs used in our country are constructed of earth dams. A topical issue is the study of the influence of filtration processes on groundwater dams, occurring both on the dam body and on its bottom. Therefore, the study and evaluation of the filtration water content in the water body runoff is of great importance for the prevention of suffosion phenomena. During the naturalscientific field studies, measurements of seepage water coming from the dam of the Chimkurgan reservoir were carried out at 19 gauging stations. When determining the amount of dry residues in water samples taken from each gauging station, the results at gauging stations 3A, 4, and 7 were very close to the upstream water level. However, at the other gauging stations, these values were at much higher levels. The pH levels of the samples obtained were checked using a pH Meters instrument, and it was found that they were not significantly different from each other. The spectrophotometric device was used to determine the turbidity of the seepage waters, and it was found that the turbidity was higher in the samples taken from gauging stations 1, 4, 4a, 5, 6, 7, 7b, and 8a. The results obtained from this study show that studying the composition of seepage water in dams and evaluating the seepage process are important tasks. This ensures the reliable operation of earth dams.
