Calculation results show that peaks of the maximum principal stresses move toward the surface of chamber after reinforcement, with the self-bearing capacity of rock increased and the plastic zone decreased. In addition, displacement of walls reaches 41.4 mm, that of roof, 22.1 mm, and that of heave, 6.45 mm. Further more, force of supports is in a rational scope.

采用FLAC(上标 3D)软件对原支护方案和返修加固方案进行了数值模拟，结果表明：修复加固后，最大主应力峰值外移，塑性区范围减小，围岩承载能力增强，两帮移近量41.4mm，顶板移近量22.1mm，底鼓量6.45mm，支护受力合理。

Results Same conservative sites and key catalytic sites existed among SjLDH and LDHs from other species. Similarity of SjLDH compared to CsLDH, TvLDH and HsLDH was 75%, 17%, 58%-60% respectively. Phylogenetic analysis demonstrated that the evolution relation between SjLDH and DmLDH was closer than the relation between SjLDH and CeLDH, the relationship between SjLDH and HsLDH-B,-C was closer than HsLDH-A. Three trans-membrane regions were found, the region of 98aa-106aa in three hydrophilia regions located outside of membrane was inferred as the major antigen epitope. This antigen epitope had significant difference with LDHs from protozoon （ Pf ., Tg ., Tv .） and had 1-3 amino acid residue difference with MmLDH, HsLDH-A,-B,-C, and was the same with CsLDH. One of the key catalytic residues and substrate binding loop were located in this region. Tertiary structure demonstrated that 98aa-106aa was on the surface of the protein and formed a substrate binding loop, other two key catalytic sites were at the position near the loop.

结果 SjLDH与其他物种的同源序列含相同的保守位点及催化活性位点，与华支睾吸虫LDH同源性最高为75％，与阴道毛滴虫LDH同源性最低为17%，与人LDH（HsLDH-A，-B，-C）的同源性为58%~60％； SjLDH与果蝇的进化距离较秀丽隐杆线虫为近，3种人LDH中与HsLDH-B、-C的进化距离较HsLDH-A为近；该蛋白具有3个跨膜区域，3个高亲水性区域，主要的线性表位98aa~106aa位于膜外，与原虫LDH相同区域差异显著，而与其他LDH有1~3个氨基酸的差异，关键催化位点之一及底物丙酮酸结合区域位于该区域，蛋白质同源模建分析表明该区域位于蛋白表面形成环状结构，3个关键催化位点位于该区域或在其附近。
