国内层状盐岩具有夹层多、不溶物含量高等特点，现有造腔软件不能很好地模拟国内层状盐岩水溶造腔过程。基于流体力学和化学动力学等理论，建立能够描述盐岩造腔过程的数学模型，并提出了夹层垮塌判据。结合国内层状盐岩水溶造腔工艺特征，开发出能模拟含夹层盐岩水溶造腔的软件Salt Cavern Builder V1.0。该软件可模拟纯盐岩、多夹层盐岩的水溶造腔过程，能较好地反映出造腔方案在现场造腔过程中每个阶段的实施效果。通过大尺寸型盐造腔相似试验，模拟无夹层和含单一夹层的腔体形状扩展过程。基于相似理论基础，在现场造腔工艺条件下，造腔软件模拟出的结果与试验得到的结果接近，验证了该软件的实用性。

Multi-interlayer and large amount of unsolvable materials are the China’s salt rock’s specialties, so that the current software is not able to simulate the process that how domestic layered salt rock cavity built clearly .By using the theory of hydrodynamics and chemical kinetics, a mathematical model which has excellent ability to describe the cavity building process of salt rock, and a criterion of interlayer collapse are proposed. Then by combining the specificity of the domestic washing techniques , an improved simulation software:Salt Cavern Builder V1.0 is developed. This software has the ability to simulate the cavity building process of pure salt rock and multi-layered salt rock. This software has outstanding capability to present the result in every step for designing cavity-building scheme. By testing the process of similar cavity-building experiments for large-size molded salt rock, the cavity-expansion processes for both none-layered and simple-layered salt rock are simulated successfully. Based on similar theory, this cavity-building simulation software can obtain satisfactory result under the condition of the cavity-building technique in the field. The result is very closed to the one produced by real experiment, so as to verify the practicality of this software.
