在地下坑道工程的构筑中,有时需在洞室围岩与衬砌之间进行回填。本文阐明了把用浆砌块石改为用一种压缩性大,能较多吸收能量的材料进行回填,不但可以提高衬砌的承载能力,而且还可以充分发挥岩体的承载能力。
In the construction of underground tunnel works, it is sometimes necessary to backfill the surrounding rock and lining of the cavern. This paper clarified that the use of mortar block rock instead of backfilling with a material with high compressibility and high energy absorption capacity can not only increase the bearing capacity of the lining, but also give full play to the bearing capacity of the rock mass.
