大地測量學(xué)實(shí)習(xí)報(bào)告分解

6.1圖根控制測量 -8-6.2碎步測量： -9- 本次實(shí)習(xí)的是在我們完成《大地測量學(xué)基礎(chǔ)》這門課程之后進(jìn)行的，通過完成水準(zhǔn)儀有關(guān)一起的檢驗(yàn)和二等水準(zhǔn)測量，使我們熟悉儀器的操作，并在實(shí)習(xí)過程中鍛煉我們的實(shí)際動手能力，提升團(tuán)隊(duì)協(xié)作能力以及鞏固我們在課堂所學(xué)的理論知識。另外，在后期的編程和外業(yè)概算過程中，對我們的發(fā)現(xiàn)問題、提出問題、解決問題的能力得到一次提升，為今后進(jìn)入共有三個(gè)已知點(diǎn)可選用，我組所用點(diǎn)為珞珈山環(huán)的教務(wù)部點(diǎn)，已知高程為126.157m。后前差左邊表格均為往測，光學(xué)儀器返測時(shí)與往測相反，數(shù)字水準(zhǔn)儀返測與七．使用的儀器與儀器檢驗(yàn)），水準(zhǔn)線路圖見附錄，觀測日期與觀測時(shí)段在觀測記錄薄中記載詳細(xì)。正算是指：由大地坐標(biāo)（L,B）求得高斯平面坐標(biāo)由第一個(gè)條件可知，中央子午線東西兩側(cè)的投影必然對稱于中央子該等于投影前從赤道量至該點(diǎn)的子午弧長。S）：{doublePI=3.1415926535897Bhudu=(m_du2*3600+m_fen2*60+m_miao2)*2*PI/360/3600L=m_du1*3600+m_fen1*60+N=6399698.902-(21562.267-(108.973-0.612*cos(Bhudu)*cos(Bhudu))*coudu)*cos(Bhudu))*cos(Bhudu)*ca0=32140.404-(135.3302-(0.7092-0.0040*cos(Bhudu)*cosu)*cos(Bhudu))*cos(Bhudu)*ca4=(0.25+0.00252*cos(Bhudu)*cos(Bhudu))*cos(Bhudu)*c;a6=(0.166*cos(Bhudu)*cos(Bhudu)-0.084)*cos(Ba3=(0.3333333+0.001123*cos(Bhudu)*cos(Bhudu))*cos(Bha5=0.0083-(0.1667-(0.1968+0.0040*cos(Bhudu)*cos(Bhudm_x1=6367558.4969*Bhudu-(a0-(0.5+(a4+a6*l*l)*l*l)*l*l*N)*sin(Bhm_y1=(1+(a3+a5*l*l)*l*l)*l*N*cos(Bhudu)+5}{doublePI=3.1415926535897doublex,y,Bf,Be,l,Bf=Be+(50221746+(293622+(2350+22*cos(Be)*cos(Be))*cos(Be)*cos(Nf=6399698.902-(21562.267-(108.973-0.612*cos(Bf)*cos(Bf))*cos(Bf)b2=(0.5+0.003369*cos(Bf)*cos(Bf))*sin(Bfb3=0.333333-(0.166667-0.001123*cos(Bf)*cos(Bf))*cos(Bfb4=0.25+(0.16161+0.00562*cos(Bf)*cos(Bf))*cos(Bfb5=0.2-(0.1667-0.0088*cos(Bf)*cos(Bf))*cos(BfB=(Bf-(1.0-(b4-0.12*Z*Z)*Z*Z)*Z*Z*b2)/2/(PI)*36m_fen3=(int)((L-(int)Lm_miao3=L*3600-m_du3*3600-m_fem_fen4=(int)((B-(int)Bm_miao4=B*3600-m_du4*3600-m_fe}{doubleBf,tf,Nf,r12,nf,BhuUpdateData();h1=m_h1,h2=m_h2;x1=m_x1,y1=m_y1-500000,x2=m_x2,y2=m_y2-500000;B1=(m_B1du+m_B1fen/60+m_B1miao/3600)*PI/180;B2=(m_B2du+m_B2fen/60+m_B2miao/3600)*PI/180;n1=sqrt(eep*cos(B1)*cos(B1));n2=sqrt(eep*cos(B2)*cos(B2));M1=a*(1-ee)/sqrt((1-ee*sin(B1)*sin(B1))*(1-ee*sin(B1)*sin(B1))*(1-ee*N1=a/sqrt(1-ee*sin(B1)*sin(BM2=a*(1-ee)/sqrt((1-ee*sin(B2)*sin(B2))*(1-ee*sin(B2)*sin(B2))*(1N2=a/sqrt(1-ee*sin(B2)*sin(Bq12=-(x2-x1)*(2*y1+y2-ym*ym*ym/(R1*R1))/(6*R1*R1)Bf=Bhudu+(50221746+(293622+(2350+22*cos(Bhudu)*cos(Bhudu))*cos(Bhudu)*cos(Bhudu))*cos(Bhudu)*cos(Bhudu))*1.0e-10*sin(Bhudu)*cos(Bhudunf=sqrt(eep*cos(Bf)*cos(Bf));Nf=a/sqrt(1-ee*sin(Bf)*sin(Bf));r12=y1*tf/Nf-y1*y1*y1*tf*(1+tf*tf-nf*nf)/(3*Nf*Nf*Nf)+y1*y1*y1*y1*y1*tf*(2+5*tf*tf+3*tf*tf*tf*tf)/(15*Nf*Nf*Nf*Nf*Nf);A12=a12+r12-q12;R1=M1*N1/(N1*cos(A12)*cos(A12)+M1*sin(A12)*sin(A12));}while(fabs(Rm-R1)>=1.0e-10);A12=A12*180/PI;//化度m_A12du=(int)A12;m_A12fen=(int)((A12-(int)A12)*60);m_A12miao=A12*3600-m_A12du*3600-m_A12fen*60;UpdateData(FALSE);}voidCMyDlg::OnButton2(){doublePI=3.14159265358979323846264338327950288;UpdateData();h1=m_h1,h2=m_h2;x1=m_x1,y1=m_y1-500000,x2=m_x2,y2=m_y2-500000;B1=(m_B1du+m_B1fen/60+m_B1miao/3600)*PI/180;B2=(m_B2du+m_B2fen/60+m_B2miao/3600)*PI/180;A1=(m_A12du+m_A12fen/60+m_A12miao/3600)*PI/180;N1=a/sqrt(1-ee*sin(B1)*sin(B1));RA=N1/(1+eep*cos(B1)*cos(B1)*cos(A1)*cos(A1));H1=m_h1+m_h0;H2=m_h2+m_h0;f=1-(H2-H1)/D*(H2-H1)/D;S=D*sqrt(f/(f1*f2))+D*D*D/(24*RA*RA);Bm=0.5*(B1+B2);Mm=a*(1-ee)/sqrt((1-ee*sin(Bm)*sin(Bm))*(1-ee*sin(Bm)*sin(Bm))*(1-ee*Nm=a/sqrt(1-ee*sin(Bm)*sin(Bm));Rm=sqrt(Mm*Nm);D12=(1+ym*ym/(2*Rm*Rm)+(y2-y1)*(y2-y1)/(24*Rm*Rm)+ym*ym*ym*ym/(24*Rm*Rm*Rm*Rm))*S;m_S=S;m_D12=D12;UpdateData(FALSE);}voidCMyDlg::OnButton1(){//TODO:AddyourcontrolnotificationhandlercodeheredoublePI=3.1415926535897B1,L1,A12,S12,M1,N1,t,n,dertB0,dertL0,dertA0,Bm,Lm,Am,dertB,deB1=(m_B1du+m_B1fen/60+m_B1miao/3600)*PI/180L1=(m_L1du+m_L1fen/60+m_L1miao/A12=(m_A12du+m_A12fen/60+m_A12miao/3600)*PI/M1=a*(1-ee)/sqrt(f1*f1*N1=a/sqrt(1-ee*sin(B1)*sin(BMm=a*(1-ee)/sqrt(f2*f2*Nm=a/sqrt(1-ee*sin(Bm)*sin(BVm=sqrt(1+eep*cos(Bm)*cof4=3*cos(Am)*cos(Am)*nm*nm*(tm*tm-1-f3=1+S12*S12/(24*Nm*Nm)*(sin(Am)*sin(Am)*(2+f4=tm*tm*sin(Am)*sin(Am)-cos(Am)*cos(Am)*(1+nm*nf4=cos(Am)*cos(Am)*(2+7*nm*nm+9*nm*nm*tm*tm+5*nm{f4=3*cos(Am)*cos(Am)*nm*nm*(tm*tm-1-f3=1+S12*S12/(24*Nm*Nm)*(sin(Am)*sin(Am)*(2+f4=tm*tm*sin(Am)*sin(Am)-cos(Am)*cos(Am)*(1+nm*nf4=cos(Am)*cos(Am)*(2+7*nm*nm+9*nm*nm*tm*tm+5*nmMm=a*(1-ee)/sqrt((1-ee*sin(Bm)*sin(Bm))*(1-ee*sin(Bm)*sin(Bm))*(1Nm=a/sqrt(1-ee*sin(Bm)*sin(BVm=sqrt(1+eep*cos(Bm)*co}while(((dertB-dertB0)>1.0e-10)||((dertL-dertL0)>1.0e-10)||((dertA-m_B2fen=(int)((B2-(int)B2m_B2miao=B2*3600-m_B2du*3600-m_B2fm_L2fen=(int)((L2-(int)L2m_L2miao=L2*3600-m_L2du*3600-m_L2fm_A21fen=(int)((A21-(int)A21m_A21miao=A21*3600-m_A21du*3600-m_A21f}{doublePI=3.1415926535897doubleB1,L1,B2,L2,Bm,dertB,dertA,dertL,Mm,Nm,r01,r21,r03,s10,s12,s30,t01,t21,t03,Am,U,Vm,V,tm,nm,T,C,S,A1,A2,f1;UpdateData();B1=(m_b1du+m_b1fen/60+m_b1miao/3600)*PI/180;//化弧度L1=(m_l1du+m_l1fen/60+m_l1miao/3600)*PI/180;B2=(m_b2du+m_b2fen/60+m_b2miao/3600)*PI/180;//化弧度L2=(m_l2du+m_l2fen/60+m_l2miao/3600)*PI/180;Bm=0.5*(B1+B2);dertB=B2-B1;dertL=L2-L1;f1=1-ee*sin(Bm)*sin(Bm);Mm=a*(1-ee)/sqrt(f1*f1*f1);Nm=a/sqrt(1-ee*sin(Bm)*sin(Bm));nm=sqrt(eep*cos(Bm)*cos(Bm));tm=tan(Bm);Vm=sqrt(1+eep*cos(B
