在砂质粉土液化层中要慎重选择桩型杭州南阳经济开发区阳城热电厂的工程场地，是２０多年前围海筑填而成的地带，地下水位高、孔隙比大、地层稳定性差，场内地质条件以砂质粉土为主，且已达到饱和状态，天然含水量达２２％～３１％，孔隙比０．７左右，经采用跨孔剪切波原... The site of the Yangcheng Thermal Power Plant in Hangzhou Nanyang Economic Development Zone should be carefully selected in the liquefaction layer of sandy silt soil. It is a zone constructed by the sea more than 20 years ago. It has a high groundwater level, a large void ratio, and poor stability of the formation. The site geological conditions are dominated by sandy silt, and have reached a saturated state, with a natural moisture content of 22% to 31%, a porosity ratio of about 0.7, and the use of cross-hole shear wave...
