Construction of moorings on loose soils having artificiallyimproved physical-mechanical characteristics СТРОИТЕЛЬСТВО ПРИЧАЛОВ НА СЛАБЫХ ГРУНТАХ ОСНОВАНИЯ С ИСКУССТВЕННО УЛУЧШЕННЫМИ ФИЗИКО-МЕХАНИЧЕСКИМИ ХАРАКТЕРИСТИКАМИ
This paper covers the technology of stabilization of loose soils through the employment of silt-cement piles, or the so-called deep soil stabilization technology. It is applicable to various types of loose soils, including clay, sapropel, silt and peat. However, geotechnical and chemical properties of soils surely affect the stabilization efficiency and the choice for the stabilization material.The authors provide a brief overview of the soil stabilization technology employing silt-cement piles and based on the principle of dry mixing of water-saturated natural soil with cement. Thus, dry powder enters into the chemical reaction with the stream of water to reduce the content of water in the soil. The research into the bearing capacity of siltcement piles and the stabilized territory of moorings was performed in the Temryuk port.The co-objective of the research was to identify the operating conditions of cargo moorings in the Temryuk port constructed on loose soils. All conclusions were based on the field data, seismometric and laboratory tests. The analysis of and research into the operating conditions of moorings demonstrate the efficiency of the long-term operation of berthing facilities constructed on the soils stabilized by silt-cement piles. This methodology can be used to stabilize port territories, road beds of railways and highways constructed on loose soils.The authors also elaborate on the potential upgrade of categories of cargo moorings constructed on loose soils and stabilized by silt-cement piles. Calculation results and researches demonstrate that it is quite difficult to significantly upgrade loading categories in respect of open warehouse spaces, as silt-cement piles of the pre-set diameter cannot provide for the bearing capacity corresponding to the first category loading. The solution may consist in the change of the stabilization design with account for the thixotropic properties of clay soils. Structural solutions may consist in the selection of the pile foot designs that may stabilize loose clay soils, on the one hand, and meet the loading requirements, on the other hand.
Рассмотрена технология закрепления слабых грунтов основания илоцементными сваями. На основании натурных данных и лабораторных исследований проведен анализ эксплуатационного состояния построенных на слабых грунтах грузовых причалов в порту Тюмрюк. Рассмотрен вопрос о возможности повышения категории грузовых причалов, построенных на слабых основаниях и армированных илоцементными сваями.
