Underground Water Level

Canal bridge and aqueduct main foundation types include well column, pier, bored piles, bent pile etc. Most of these foundations are in low-lying conduit. The water content of foundation soil is very rich. Especially pile foundation in the drain, due to the high underground water level, pile foundation around soil is in a state full of water. So such type of foundation freeze injury phenomenons are very serious. In order to solve such freeze injury problems, some antifreezing measures are adopted.

Seasonal Frozen Soil

The seasonal permafrost is widely distributed in China. Seismic Design Code (GB50011-2010) assumes that the soil temperature is above 0°C, which lacks the analysis of seasonally frozen soil. This article considered various sources of shear wave velocity variability and the frozen depth variability and calculated the ground response spectrums of the sites with seasonal frozen soil. The results shows that when Class1 and Class2 venues with thinner overlying soil and higher shear wave velocities their peaks of response spectrum with frozen soil will higher than that without permafrost. In the design the spectrums with frozen soil need to be calculated independently. In Class 3 and Class4 venues the response spectrums are essentially coincident, so the design only need calculate the spectrums under normal condition.

Research on frost heaving of high speed railway subgrade filling in seasonal frozen soil area is developed indoor. Through freezing and thawing strength and frost heaving amount test, the research analyzes factors affecting frost heaving of subgrade filling, points out that water content, fine stuff admixing amount and plasticity of fine-grained soil have relatively large influence on frost heaving, while freezing temperature and freezing and thawing cycle index have relatively small influence. Water content is main factor to have effect on frost heaving of subgrade filling. When the water content reaches to some certain value, even coarse-grained soil can produce considerable frost heaving amount. Therefore, taking effective waterproof and drainage measures is of great importance in subgrade frost heaving prevention and treatment.
