WJP

Burying earth pressure cell under the base of WJP to measure pile end stress, and doing the loading test in 28d, pile strength indexes in different conservation temperature and soil horizon can be obtained.

在桩底预埋土压力盒测量桩端应力，并在28d龄期进行载荷试验，得到不同养护温度、不同土层下的桩体强度指标。

Model foundation is built in model shafts of laboratory test tank and WJP is drived in different soil horizons temperature.

在室内试验模型槽内构筑模型地基，在不同的土层温度下打设湿喷桩。

Via the indoors model tests simulating the realistic projects, the cores of the tests are exact emersion of the process of making piles and the environments of the WJP composite foundation.

论文的开展基于模拟工程现场实际的基础上而进行的室内模型湿喷桩复合地基试验。

The essences of the thesis are to quantitative research on the model WJP and Its composite foundation by changing soil and temperature parameter.

本论文拟以连盐高速公路（盐城段）湿喷桩复合地基为研究背景，重点开展地场温度和土层变化对湿喷桩及其复合地基影响的室内模型试验和分析研究。
