Dissolution pores have a notable impact on the mechanical behavior of rock masses. Understanding the mechanisms by which dissolution pores influence the mechanics of rock is crucial for various engineering projects, including slope and foundation stability and related disaster mechanisms. Dissolved pores can be divided into two main types: honeycomb- and wormhole-like pores. In this study, a random algorithm was used to create discrete-element rock samples with different dissolution pore structures. Two characteristic dissolution parameters (rate of dissolution(k) and dissolution density coefficient (u)) were defined. They were used to describe the dissolution characteristics. We analyzed the internal stress, uniaxial compressive strength, crack propagation, and failure mode characteristics of the dissolved rock samples during the loading process. The results showed that rocks with different dissolution pore structures exhibit distinct mechanical behavior. Wormhole-like porous rock samples have higher uniaxial compressive strength and strength variability due to their different stresses. Furthermore, the uniaxial compressive strength of the dissolved rock is a function of the characteristic dissolution parameters. The deformation process of the porous dissolution sample was divided into four stages: (1) elastic deformation, (2) unstable fracture development, (3) post-peak strain softening, and (4) failure. Cracks in honeycomb-like dissolution rock were mainly initiated at the pore poles, and the failure mode was a shear failure, whereas cracks in the wormhole-like dissolution rock were mainly initiated at the pore poles and sidewalls, and the failure was rock crushing failure.

溶蚀孔隙对岩体的力学行为有显着影响。了解溶蚀孔隙影响岩石力学的机制对于各种工程项目（包括边坡和地基稳定性以及相关灾害机制）至关重要。溶孔可分为两种主要类型：蜂窝状孔和虫孔状孔。在本研究中，使用随机算法创建具有不同溶蚀孔隙结构的离散元素岩石样品。定义了两个特征溶出参数（溶出速率（k）和溶出密度系数（u ））。它们用于描述溶出特性。分析了加载过程中溶岩样品的内应力、单轴抗压强度、裂纹扩展和破坏模式特征。结果表明，不同溶蚀孔隙结构的岩石表现出不同的力学行为。类虫孔多孔岩石样品由于应力不同，具有较高的单轴抗压强度和强度变异性。此外，溶解岩石的单轴抗压强度是特征溶解参数的函数。多孔溶解样品的变形过程分为四个阶段：（1）弹性变形，（2）不稳定裂缝发展，（3）峰后应变软化，（4）破坏。蜂窝状溶蚀岩裂缝主要萌生于孔隙极点，破坏模式为剪切破坏；虫孔状溶蚀岩裂缝主要萌生于孔隙极点和侧壁，破坏方式为岩石破碎破坏。
