Introduction Rock destruction processes are fundamental to industries such as mining, quarrying, and civil construction, where the mechanical breakdown of geological materials is required to extract resources or create infrastructure [1, 2].
Studies indicate that suboptimal tool designs can result in energy losses of up to 25% during rock cutting, highlighting the potential for improvements through better engineering solutions [11, 12].
Methods The study of energy consumption in rock destruction has been a focal point in mining and geotechnical engineering, with foundational theories providing insights into the mechanics of material fracture and tool performance [16, 17].

Simulating and Testing Study on Construction Temporal-spatial Effect of six lanes Multi-arch Tunnel Xiaoguang Jin1, 2, a, Bingwei Cui1, 2, b, Mengjun Wu3, c 1School of Civil Engineering, Chongqing University, Chongqing 400045, China; 2Key Laboratory of New Technology for Construction of Cities in Mountain Area (Chongqing University), Ministry of Education, Chongqing 400045, China; 3China Merchants Chongqing Communications Research & Design Institute Co., Ltd., Chongqing, 400067, China; aJxgcqu@163.com, bCuibw2009@126.com, cWumenjun@ccrdi.com Keywords: six lane multi-arch tunnel; temporal-spatial effect; numerical simulation; model testing Abstract: Owing to several construction procedures of bidirectional 6 lane multi-arch tunnel, with the characteristics of large dig span and flat cross section, the wall rock and support structure of which will be repeatedly disturbed by multiple excavations, so their mechanical and deformational features are remarkably complicated.
Based on engineering geology survey report details, selecting K48+510 for calculation cross section, numerical model is established.

Currently, the constructed wetlands have been used to control the lakes that are polluted and lost the capability of natural recovery and to keep the stability of reservoir water and other engineering projects.
With the ecological technology or ecological engineering, people can change and eliminate the unfavorable factors that restricted the development of wetland's ecosystem, reproduce the structure and function of pre-disturbance, restore wetland's related physical, chemical and biological characteristics, and make Ruian healthy development.
