Description

technical field [0001] The invention relates to a rock-soil dry-wet cycle test device, in particular to a rock-soil dry-wet cycle test device for simulating marine environment and acid-base corrosion. Background technique [0002] Soft soil foundations are widely distributed in the coastal areas of China. Due to their low bearing capacity and large deformation, they often have a negative impact on the stability and safety of engineering structures. With the rapid development of society, more and more infrastructure projects are built in soft soil areas, and it is becoming more and more important to study soft soil solidification, especially the research on soft soil treatment near the coastal environment or in saline-alkali land is very important and complex. In the indoor test, it is necessary to study the strength characteristics of soft soil solidification by simulating the seawater dry-wet cycle test or the acid-base cycle test. [0003] At present, the test methods fo...

However, the labor intensity of this method is high, and in the process of human movement, it is easy to trip and cause damage to the sample, thereby affecting the accuracy of the test data; 2. Although the existing dry-wet cycle device does not require manual labor The automatic process of dry-wet cycle of the sample is realized, but the current control dry-wet cycle device cannot simulate a similar seawater environment, such as the rising and falling tides of seawater and the surge of seawater, so that the data lacks the rising tide of seawater And ebb tide and seawater surge influence factors on the soft soil after solidification, which greatly affects the accuracy of the data
