Vacuum-Surface Combined Preloading Method for Consolidation of Soft Ground FAN Xin-Rong, YE Hai-Xia (Luoyang Construction Engineering Company, Luoyang, Henan 471003, China) The vacuum preload can make the foundation produce a large settlement rate, and at the same time improve the stability of roadbed and lateral displacement. The correlation between displacement rate and load size is obvious. 1 Overview In highway construction, it is often encountered geologically a new Q4 soil in the 4th epoch, mostly saturated compacted clay. The types of soil are mostly silt, silty clay, and silty sub-clay. This type of soil has high water content, large pores, low density, low strength, high compressibility, and low water permeability. Such ground consolidation is slow, and it is easy to produce large differential settlement. In addition, due to the low strength foundation bearing capacity and stability described. 2 Engineering Geological Conditions The surface layer of this section is a 1.5m 3.5m thick pond deposit with soft plastic and hard plastic subclay, the upper part is a siltous clay subclayer with a thickness of 14.0m20.0m, and the lower part is a soft plasticized hard clay with gravel and clayey soil. Gravel, under the bedrock,. Roadbed pile 4 load application process The test section began vacuuming on August 1, 2002, and unloaded vacuum on April 17, 2003. The application of vacuum load was as shown. Embankment is loaded from Every service we provide has high praise from customers, life-long after-sales maintenance, rest assured shopping, packaged delivery, five-year warranty, damaged package, cooperation with many well-known brands at home and abroad, and a variety of varieties for you to choose.
