Research to improve the management of tunneling operations in urban areas of Vietnam
Authors(3) :-Tran Duc Thuan, Le Hoai Linh, Tuan Anh Nguyen
Nowadays, in Vietnam's major cities, making use of underground space (tunnels) in road traffic is necessary, especially at river crossings or at complex intersections with high traffic density. However, there have been many problems in the operation, exploitation and maintenance of traffic tunnels due to damages such as cracks in the tunnel shell, water infiltration, flooding, fire and explosion, causing traffic insecurity, which needs to be further considered and perfected, especially the safety of people and vehicles traveling through the tunnels. The drafting of management procedures for tunnel works has some limitations in the operation process, because the tunnel operation process contains many potential risks that can lead to risks affecting the function, the existence of the work and the damage to human life and property, the cost and time for the maintenance. This article focuses on perfecting the management process of tunneling operations in order to contribute to ensuring stability, longevity, workability and efficiency when operating tunnels in general and urban traffic tunnels in particular

Experimental Investigation of a Self-Healing Concrete Considering Bacillus Megaterium Bacteria and Fibres
Authors(3) :-Vandana Bhargava, Akhilesh Sharma, Sandeep Gupta
It is strong enough to resist compressive load but prone to cracking due to weak in tension which ultimately reduce the life of structure. Hence, any effort to improve the life span of structure will indirectly improve the sustainability of the environment. Cracks in concrete lead to ingress of chemicals in to concrete structure resulting in lower strength and durability. To increase the durability of the structure either cracks are repaired which is expensive or provide extra reinforcement to ensure the cracks width stays within certain limit. Only for durability reason, this extra steel is not desirable. One way to increase the durability of structure and reduce such extra cost is to use self-healing concrete. Self- healing of concrete is any process by the material itself involving the recovery and hence improvement of performance after an earlier action that had reduce the performance of material. In this study we are mixing Bacillus Megaterium bacteria with fibers in concrete with the motive to enhance its self healing properties with strengthening. Here it is concluded that with bacteria concrete become more resisting to weathering effect and have capability to self heal with addition of fibers become comparatively more durable and load bearing.
