Ke Ming Wu, Zicheng Zhang, Muer Tie, Zubin Ai et autres

VINGS-Mono is a monocular (inertial) Gaussian Splatting (GS) SLAM framework designed for large scenes. The framework comprises four main components: VIO Front End, 2D Gaussian Map, NVS Loop Closure, and Dynamic Eraser. In the VIO Front End, RGB frames are processed through …

Ventilation characteristics of high ground temperature tunnels

Zubin Ai, Zhensheng Cao, Shengjun Hou, Chenchen Jiang et autres

There are a few types of research on the ventilation characteristics of high temperature and high drop spiral tunnels. To study the influence of the slope, curvature radius, and ambient temperature on the ventilation characteristics of high temperature spiral tunnel during operation, …

A Comparative Study of Soft Rock Tunnel Control Methods Using NPR High Preload Anchor Cables: Analysis of Multiple Cases

Xiaowu Zhou, S.‐H. Yang, Zhiguo Ma, Zubin Ai et autres

Addressing the challenge of large deformation in soft rock tunnels is an urgent imperative. The conventional support method is mainly passive or low-stress compensation support, which proves inadequate in effectively managing the large deformation disaster of soft rock under complex geological conditions. …

A review of the durability of joints in concrete structures

Zubin Ai, Song Yang, Feipeng Ruan, Yin Zhong Shen et autres

Durability of concrete on bridges has been widely investigated over the past decades. Most of the studies focus on monolithic concrete without considering the effect of joints (e.g., direct wet joint; roughened wet joint; dry joint; epoxied joint) caused by various construction …

Analytical Solutions for the Mechanical Responses of Shallow Double‐Arched Tunnel Subjected to Symmetric Loads

Song Yang, Rui Dai, Zubin Ai, Xiaochang Li et autres

Double‐arched tunnel is a special kind of tunnel structure which is widely adopted for shallow rock tunnels. The internal forces within a double‐arched tunnel are difficult to be determined due to its special geometry and complex interactions with surrounding rock masses. This …
