“…In the process, the image, state and efficacy of the products will be introduced. Integrating the product concept with the whole life cycle of digital construction of power grid enterprises can further expand the actual coverage of the whole life cycle, improve and optimize the digital construction structure from multiple angles, design a more flexible and changeable whole life cycle construction structure, and strengthen the practical effect of digital construction of power grid enterprises [6] .

At present, the whole life cycle management stage of digital construction of power grid enterprises is generally set in one-way form, and the limitation of the control scope of power enterprises leads to the decline of the optimal ratio of life cycle management. Therefore, this paper puts forward the design and verification research on the whole life cycle of digital construction of power grid enterprises based on product concept. First, we can design the idea of life cycle management, adopt a multi-objective approach, break the restrictions on the control scope of electric power enterprises, establish a digital life cycle management stage of multi-objective enterprises, design a product concept life cycle management model based on this, and adopt a "demand library" to track and control and strengthen the practice of life cycle construction. The test results show that the final optimal ratio of life cycle management can reach above 16 for the 7 selected life cycle management test unit areas, which shows that with the assistance and support of product concepts, the currently designed life cycle practice management mode of digital construction of power grid enterprises is more flexible, changeable and effective, which can ensure the life cycle practice and effect of digital construction of power grid enterprises in different background environments and has practical application value.

“…The PFE-IE method can be applied to analyze the dynamic stability of a high steep rock slope [28,29] and can be coupled with the smoothed particle hydrodynamics (SPH) method to investigate the effects of a landslide-generated wave (LGW) for the the safety of reservoir areas [30]. As an improvement to the PFE-IE method, the PRE-IE method also has the potential to solve these problems.…”

The stability analysis of rock slopes has been a prominent topic in the field of rock mechanics, primarily due to the widespread occurrence of discontinuous structural planes in rock masses. Based on this complex characteristic of rock slopes, this paper proposes a novel numerical method, the Partitioned-Rigid-Element and Interface-Element (PRE-IE) method. In the PRE-IE method, the structure is modeled as several rigid bodies and discontinuous structural planes, which are, respectively, divided into partitioned rigid elements and interface elements. Taking the contact force of node pairs and the displacement of the rigid body centroid as mixed variables, according to the principle of minimum potential energy, the governing equations of PRE-IE can be established using the Lagrange multiplier method and then solved using the nonlinear contact iterative method and the incremental method. A classic case study demonstrates that using the failure of all contact node pairs as the criterion for slope failure is appropriate. This criterion is objective and avoids the potential impact of personal bias on safety factor calculations. Two numerical examples of differently shaped slopes are provided to verify the correctness and validity of the PRE-IE method. By comparing the safety factor calculated using the PRE-IE method with those obtained from other different methods, as well as comparing the computational time, it is shown that the PRE-IE method, in combination with the SRM, can accurately and efficiently analyze the stability problems of rock slopes.
