温度场和渗流场耦合对恐龙化石风化破坏的影响

Effect of Coupling of Temperature Field and Seepage Field on Weathering Damage of Dinosaur Fossils

摘要:

在恐龙化石经受风化破坏过程中，温度和水是起作用的两大主要因素。为了深入探讨恐龙化石风化破坏机理，有效、科学、合理地保护恐龙化石，该文将恐龙化石及围岩作为岩体，运用岩体水力学研究中温度场与渗流场之间的耦合关系，研究温度和水在恐龙化石风化破坏过程中的内在机制。通过建立温度场与渗流场数值模型，模拟温度场与渗流场在恐龙化石风化过程中的相互作用，定性分析了温度与水相互作用对化石风化的破坏机理。

Abstract:

Temperature and water are two main factors affecting the weathering of dinosaur fossils. In order to study the mechanism of weathering and destruction of dinosaur fossilsand protect dinosaur fossils more effectively, scientifically and reasonably, taking dinosaur fossils and surrounding rocks as rock masses, by using the coupling relationship between temperature field and seepage field, the intrinsic mechanism of temperature and water in the process of weathering and destruction of dinosaur fossils has been studied. The interaction between temperature field and seepage field in the weathering process of dinosaur fossils has been simulated by establishing a numerical model of temperature field and seepage field. The destruction mechanism of the interaction between temperature and water on the weathering process of dinosaur fossils has been qualitatively analyzed.
